Add dark and light theme with OS preference support

Follow OS color scheme by default, with a three-way toggle
(System / Light / Dark) in the kebab menu. Light theme uses warm,
neutral tones with soft card-to-background contrast. Semantic colors
(damage, healing, conditions) keep their hue across themes.

Closes #10

+# Research: Action Bars Setup — Top Bar and Bottom Bar Buttons
+
+## Research Question
+
+How are the top and bottom action bars set up, what buttons do they contain, and how are their actions wired?
+
+## Summary
+
+The application has two primary bar components that frame the encounter tracker UI:
+
+1. **Top bar** — `TurnNavigation` (`turn-navigation.tsx`) — turn controls, round/combatant display, and encounter-wide actions.
+2. **Bottom bar** — `ActionBar` (`action-bar.tsx`) — combatant input, bestiary search, stat block browsing, bulk import, and player character management.
+
+Both bars share the same visual container styling (`flex items-center gap-3 rounded-md border border-border bg-card px-4 py-3`). They are laid out in `App.tsx` within a flex column, with a scrollable combatant list between them. When the encounter is empty, only the ActionBar is shown (centered in the viewport); the TurnNavigation appears with an animation when the first combatant is added.
+
+## Detailed Findings
+
+### Layout Structure (`App.tsx:243-344`)
+
+The bars live inside a `max-w-2xl` centered column:
+
+```
+┌──────────────────────────────────┐
+│  TurnNavigation (pt-8, shrink-0) │  ← top bar, conditionally shown
+├──────────────────────────────────┤
+│  SourceManager (optional inline) │  ← toggled by Library button in top bar
+├──────────────────────────────────┤
+│  Combatant list (flex-1,         │  ← scrollable
+│    overflow-y-auto)              │
+├──────────────────────────────────┤
+│  ActionBar (pb-8, shrink-0)      │  ← bottom bar
+└──────────────────────────────────┘
+```
+
+**Empty state**: When `encounter.combatants.length === 0`, the top bar is hidden and the ActionBar is vertically centered in a `flex items-center justify-center` wrapper with `pb-[15%]` offset. It receives `autoFocus` in this state.
+
+**Animation** (`useActionBarAnimation`, `App.tsx:30-66`): Manages transitions between empty and populated states:
+- Empty → populated: ActionBar plays `animate-settle-to-bottom`, TurnNavigation plays `animate-slide-down-in`.
+- Populated → empty: ActionBar plays `animate-rise-to-center`, TurnNavigation plays `animate-slide-up-out` (with `absolute` positioning during exit).
+
+The `showTopBar` flag is `true` when either combatants exist or the top bar exit animation is still running.
+
+### Top Bar — TurnNavigation (`turn-navigation.tsx`)
+
+**Props interface** (`turn-navigation.tsx:7-14`):
+- `encounter: Encounter` — full encounter state
+- `onAdvanceTurn`, `onRetreatTurn` — turn navigation callbacks
+- `onClearEncounter` — destructive clear with confirmation
+- `onRollAllInitiative` — rolls initiative for all combatants
+- `onOpenSourceManager` — toggles source manager panel
+
+**Layout**: Left–Center–Right structure:
+
+```
+[ ◀ Prev ] | [ R1  Active Combatant Name ] | [ 🎲  📚  🗑 ] [ Next ▶ ]
+```
+
+**Buttons (left to right)**:
+
+| # | Icon | Component | Variant | Action | Disabled when |
+|---|------|-----------|---------|--------|---------------|
+| 1 | `StepBack` | `Button` | default | `onRetreatTurn` | No combatants OR at round 1 index 0 |
+| 2 | `D20Icon` | `Button` | ghost | `onRollAllInitiative` | Never |
+| 3 | `Library` | `Button` | ghost | `onOpenSourceManager` | Never |
+| 4 | `Trash2` | `ConfirmButton` | — | `onClearEncounter` | No combatants |
+| 5 | `StepForward` | `Button` | default | `onAdvanceTurn` | No combatants |
+
+**Center section** (`turn-navigation.tsx:40-49`): Displays a round badge (`R{n}` in a `rounded-full bg-muted` span) and the active combatant's name (truncated). Falls back to "No combatants" in muted text.
+
+**Button grouping**: Buttons 2-4 are grouped in a `gap-0` div (tight spacing), while button 5 (Next) is separated by the outer `gap-3`.
+
+**Wiring in App.tsx** (`App.tsx:251-258`):
+- `onAdvanceTurn` → `advanceTurn` from `useEncounter()`
+- `onRetreatTurn` → `retreatTurn` from `useEncounter()`
+- `onClearEncounter` → `clearEncounter` from `useEncounter()`
+- `onRollAllInitiative` → `handleRollAllInitiative` → calls `rollAllInitiativeUseCase(makeStore(), rollDice, getCreature)`
+- `onOpenSourceManager` → toggles `sourceManagerOpen` state
+
+### Bottom Bar — ActionBar (`action-bar.tsx`)
+
+**Props interface** (`action-bar.tsx:20-36`):
+- `onAddCombatant` — adds custom combatant with optional init/AC/maxHP
+- `onAddFromBestiary` — adds creature from search result
+- `bestiarySearch` — search function returning `SearchResult[]`
+- `bestiaryLoaded` — whether bestiary index is loaded
+- `onViewStatBlock` — opens stat block panel for a creature
+- `onBulkImport` — triggers bulk source import mode
+- `bulkImportDisabled` — disables import button during loading
+- `inputRef` — external ref to the name input
+- `playerCharacters` — list of player characters for quick-add
+- `onAddFromPlayerCharacter` — adds a player character to encounter
+- `onManagePlayers` — opens player management modal
+- `autoFocus` — auto-focuses input (used in empty state)
+
+**Layout**: Form with input, contextual fields, submit button, and action icons:
+
+```
+[ + Add combatants... ] [ Init ] [ AC ] [ MaxHP ] [ Add ] [ 👥  👁  📥 ]
+```
+
+The Init/AC/MaxHP fields only appear when the input has 2+ characters and no bestiary suggestions are showing.
+
+**Buttons (left to right)**:
+
+| # | Icon | Component | Variant | Action | Condition |
+|---|------|-----------|---------|--------|-----------|
+| 1 | — | `Button` | sm | Form submit → `handleAdd` | Always shown |
+| 2 | `Users` | `Button` | ghost | `onManagePlayers` | Only if `onManagePlayers` provided |
+| 3 | `Eye` | `Button` | ghost | Toggle stat block viewer dropdown | Only if `bestiaryLoaded && onViewStatBlock` |
+| 4 | `Import` | `Button` | ghost | `onBulkImport` | Only if `bestiaryLoaded && onBulkImport` |
+
+**Button grouping**: Buttons 2-4 are grouped in a `gap-0` div, mirroring the top bar's icon button grouping.
+
+**Suggestion dropdown** (`action-bar.tsx:267-410`): Opens above the input when 2+ chars are typed and results exist. Contains:
+- A "Add as custom" escape row at the top (with `Esc` keyboard hint)
+- **Players section**: Lists matching player characters with colored icons; clicking adds them directly via `onAddFromPlayerCharacter`
+- **Bestiary section**: Lists search results; clicking queues a creature. Queued creatures show:
+  - `Minus` button — decrements count (removes queue at 0)
+  - Count badge — current queued count
+  - `Plus` button — increments count
+  - `Check` button — confirms and adds all queued copies
+
+**Stat block viewer dropdown** (`action-bar.tsx:470-513`): A separate search dropdown anchored to the Eye button. Has its own input, search results, and keyboard navigation. Selecting a result calls `onViewStatBlock`.
+
+**Keyboard handling** (`action-bar.tsx:168-186`):
+- Arrow Up/Down — navigate suggestion list
+- Enter — queue selected suggestion or confirm queued batch
+- Escape — clear suggestions and queue
+
+**Wiring in App.tsx** (`App.tsx:269-282` and `328-340`):
+- `onAddCombatant` → `addCombatant` from `useEncounter()`
+- `onAddFromBestiary` → `handleAddFromBestiary` → `addFromBestiary` from `useEncounter()`
+- `bestiarySearch` → `search` from `useBestiary()`
+- `onViewStatBlock` → `handleViewStatBlock` → constructs `CreatureId` and sets `selectedCreatureId`
+- `onBulkImport` → `handleBulkImport` → sets `bulkImportMode` and clears selection
+- `onAddFromPlayerCharacter` → `addFromPlayerCharacter` from `useEncounter()`
+- `onManagePlayers` → opens `managementOpen` state (shows `PlayerManagement` modal)
+
+### Shared UI Primitives
+
+**`Button`** (`ui/button.tsx`): CVA-based component with variants (`default`, `outline`, `ghost`) and sizes (`default`, `sm`, `icon`). Both bars use `size="icon"` with `variant="ghost"` for their icon button clusters, and `size="icon"` with default variant for the primary navigation buttons (Prev/Next in top bar).
+
+**`ConfirmButton`** (`ui/confirm-button.tsx`): Two-click destructive action button. First click shows a red pulsing confirmation state with a Check icon; second click fires `onConfirm`. Auto-reverts after 5 seconds. Supports Escape and click-outside cancellation. Used for Clear Encounter in the top bar.
+
+### Hover Color Convention
+
+Both bars use consistent hover color classes on their ghost icon buttons:
+- `hover:text-hover-action` — used on the D20 (roll initiative) button, suggesting an action/accent color
+- `hover:text-hover-neutral` — used on Library, Users, Eye, Import buttons, suggesting a neutral/informational color
+

+
+## Architecture Documentation
+
+The bars follow the app's adapter-layer convention: they are pure presentational React components that receive all behavior via callback props. No business logic lives in either bar — they delegate to handlers defined in `App.tsx`, which in turn call use-case functions from the application layer or manipulate local UI state.
+
+Both bars are rendered twice in `App.tsx` (once in the empty-state branch, once in the populated branch) rather than being conditionally repositioned, which simplifies the animation logic.
+
+The `ActionBar` is the more complex of the two, managing multiple pieces of local state (input value, suggestions, queued creatures, custom fields, stat block viewer) while `TurnNavigation` is fully stateless — all its data comes from the `encounter` prop.

+# Research: CSS Class Usage, Button Categorization, and Hover Effects
+
+## Research Question
+How are CSS classes used across all components? How are buttons categorized — are there primary and secondary buttons? What hover effects exist, and are they unified?
+
+## Summary
+
+The project uses **Tailwind CSS v4** with a custom dark theme defined in `index.css` via `@theme`. All class merging goes through a `cn()` utility (clsx + tailwind-merge). Buttons are built on a shared `Button` component using **class-variance-authority (CVA)** with three variants: **default** (primary), **outline**, and **ghost**. Hover effects are partially unified through semantic color tokens (`hover-neutral`, `hover-action`, `hover-destructive`) defined in the theme, but several components use **one-off hardcoded hover colors** that bypass the token system.
+
+## Detailed Findings
+
+### Theme System (`index.css`)
+
+All colors are defined as CSS custom properties via Tailwind v4's `@theme` directive (`index.css:3-26`):
+
+| Token | Value | Purpose |
+|---|---|---|
+| `--color-background` | `#0f172a` | Page background |
+| `--color-foreground` | `#e2e8f0` | Default text |
+| `--color-muted` | `#64748b` | Subdued elements |
+| `--color-muted-foreground` | `#94a3b8` | Secondary text |
+| `--color-card` | `#1e293b` | Card/panel surfaces |
+| `--color-border` | `#334155` | Borders |
+| `--color-primary` | `#3b82f6` | Primary actions (blue) |
+| `--color-accent` | `#3b82f6` | Accent (same as primary) |
+| `--color-destructive` | `#ef4444` | Destructive actions (red) |
+
+**Hover tokens** (semantic layer for hover states):
+
+| Token | Resolves to | Usage |
+|---|---|---|
+| `hover-neutral` | `primary` (blue) | Text color on neutral hover |
+| `hover-action` | `primary` (blue) | Text color on action hover |
+| `hover-destructive` | `destructive` (red) | Text color on destructive hover |
+| `hover-neutral-bg` | `card` (slate) | Background on neutral hover |
+| `hover-action-bg` | `muted` | Background on action hover |
+| `hover-destructive-bg` | `transparent` | Background on destructive hover |
+
+### Button Component (`components/ui/button.tsx`)
+
+Uses CVA with three variants and three sizes:
+
+**Variants:**
+
+| Variant | Base styles | Hover |
+|---|---|---|
+| `default` (primary) | `bg-primary text-primary-foreground` | `hover:bg-primary/90` |
+| `outline` | `border border-border bg-transparent` | `hover:bg-hover-neutral-bg hover:text-hover-neutral` |
+| `ghost` | (no background/border) | `hover:bg-hover-neutral-bg hover:text-hover-neutral` |
+
+**Sizes:**

+|---|---|
+| `default` | `h-9 px-4 py-2` |
+| `sm` | `h-8 px-3 text-xs` |
+| `icon` | `h-8 w-8` |
+
+All variants share: `rounded-md text-sm font-medium transition-colors focus-visible:outline-none focus-visible:ring-2 focus-visible:ring-primary disabled:pointer-events-none disabled:opacity-50`.
+
+There is **no "secondary" variant** — the outline variant is the closest equivalent.
+
+### Composite Button Components
+
+**ConfirmButton** (`components/ui/confirm-button.tsx`):
+- Wraps `Button variant="ghost" size="icon"`
+- Default state: `hover:text-hover-destructive` (uses token)
+- Confirming state: `bg-destructive text-primary-foreground animate-confirm-pulse hover:bg-destructive hover:text-primary-foreground`
+
+**OverflowMenu** (`components/ui/overflow-menu.tsx`):
+- Trigger: `Button variant="ghost" size="icon"` with `text-muted-foreground hover:text-hover-neutral`
+- Menu items: raw `<button>` elements with `hover:bg-muted/20` (**not using the token system**)
+
+### Button Usage Across Components
+
+| Component | Button type | Variant/Style |
+|---|---|---|
+| `action-bar.tsx:556` | `<Button type="submit">` | default (primary) — "Add" |
+| `action-bar.tsx:561` | `<Button type="button">` | default (primary) — "Roll all" |
+| `turn-navigation.tsx:25,54` | `<Button size="icon">` | default — prev/next turn |
+| `turn-navigation.tsx:47` | `<ConfirmButton>` | ghost+destructive — clear encounter |
+| `source-fetch-prompt.tsx:91` | `<Button size="sm">` | default — "Load" |
+| `source-fetch-prompt.tsx:106` | `<Button size="sm" variant="outline">` | outline — "Upload file" |
+| `bulk-import-prompt.tsx:31,45,106` | `<Button size="sm">` | default — "Done"/"Load All" |
+| `source-manager.tsx:50` | `<Button size="sm" variant="outline">` | outline — "Clear all" |
+| `hp-adjust-popover.tsx:112` | `<Button variant="ghost" size="icon">` | ghost + custom red — damage |
+| `hp-adjust-popover.tsx:124` | `<Button variant="ghost" size="icon">` | ghost + custom green — heal |
+| `player-management.tsx:67` | `<Button>` | default — "Create first player" |
+| `player-management.tsx:113` | `<Button variant="ghost">` | ghost — "Add player" |
+| `create-player-modal.tsx:177` | `<Button variant="ghost">` | ghost — "Cancel" |
+| `create-player-modal.tsx:180` | `<Button type="submit">` | default — "Save"/"Create" |
+| `combatant-row.tsx:625` | `<ConfirmButton>` | ghost+destructive — remove combatant |
+
+**Raw `<button>` elements** (not using the Button component):
+- `action-bar.tsx` — suggestion items, count increment/decrement, browse toggle, custom add (all inline-styled)
+- `combatant-row.tsx` — editable name, HP display, AC, initiative, concentration toggle
+- `stat-block-panel.tsx` — fold/close/pin/unpin buttons
+- `condition-picker.tsx` — condition items
+- `condition-tags.tsx` — condition tags, add condition button
+- `toast.tsx` — dismiss button
+- `player-management.tsx` — close modal, edit player
+- `create-player-modal.tsx` — close modal
+- `color-palette.tsx` — color swatches
+- `icon-grid.tsx` — icon options
+
+### Hover Effects Inventory
+
+**Using semantic tokens (unified):**
+
+| Hover class | Meaning | Used in |
+|---|---|---|
+| `hover:bg-hover-neutral-bg` | Neutral background highlight | button.tsx (outline/ghost), action-bar.tsx, condition-picker.tsx, condition-tags.tsx |
+| `hover:text-hover-neutral` | Text turns primary blue | button.tsx (outline/ghost), action-bar.tsx, combatant-row.tsx, stat-block-panel.tsx, ac-shield.tsx, toast.tsx, overflow-menu.tsx, condition-tags.tsx |
+| `hover:text-hover-action` | Action text (same as neutral) | action-bar.tsx (overflow trigger) |
+| `hover:text-hover-destructive` | Destructive text turns red | confirm-button.tsx, source-manager.tsx |
+| `hover:bg-hover-destructive-bg` | Destructive background (transparent) | source-manager.tsx |
+
+**One-off / hardcoded hover colors (NOT using tokens):**
+
+| Hover class | Used in | Context |
+|---|---|---|
+| `hover:bg-primary/90` | button.tsx (default variant) | Primary button darken |
+| `hover:bg-accent/20` | action-bar.tsx | Suggestion highlight, custom add |
+| `hover:bg-accent/40` | action-bar.tsx | Count +/- buttons, confirm queued |
+| `hover:bg-muted/20` | overflow-menu.tsx | Menu item highlight |
+| `hover:bg-red-950` | hp-adjust-popover.tsx | Damage button |
+| `hover:text-red-300` | hp-adjust-popover.tsx | Damage button text |
+| `hover:bg-emerald-950` | hp-adjust-popover.tsx | Heal button |
+| `hover:text-emerald-300` | hp-adjust-popover.tsx | Heal button text |
+| `hover:text-foreground` | player-management.tsx, create-player-modal.tsx, icon-grid.tsx | Close/edit buttons |
+| `hover:bg-background/50` | player-management.tsx | Player row hover |
+| `hover:bg-card` | icon-grid.tsx | Icon option hover |
+| `hover:border-hover-destructive` | source-manager.tsx | Clear all button border |
+| `hover:scale-110` | color-palette.tsx | Color swatch enlarge |
+| `hover:bg-destructive` | confirm-button.tsx (confirming state) | Maintain red bg on hover |
+| `hover:text-primary-foreground` | confirm-button.tsx (confirming state) | Maintain white text on hover |
+
+### Hover unification assessment
+
+The hover token system (`hover-neutral`, `hover-action`, `hover-destructive`) provides a consistent pattern for the most common interactions. The `Button` component's outline and ghost variants use these tokens, and many inline buttons in action-bar, combatant-row, stat-block-panel, and condition components also use them.
+
+However, there are notable gaps:
+1. **HP adjust popover** uses hardcoded red/green colors (`red-950`, `emerald-950`) instead of tokens
+2. **Overflow menu items** use `hover:bg-muted/20` instead of `hover:bg-hover-neutral-bg`
+3. **Player management modals** use `hover:text-foreground` and `hover:bg-background/50` instead of the semantic tokens
+4. **Action-bar suggestion items** use `hover:bg-accent/20` and `hover:bg-accent/40` — accent-specific patterns not in the token system
+5. **Icon grid** and **color palette** use their own hover patterns (`hover:bg-card`, `hover:scale-110`)

+
+## Architecture Documentation
+
+The styling architecture follows this pattern:
+
+1. **Theme layer**: `index.css` defines all color tokens via `@theme`, including semantic hover tokens
+2. **Component layer**: `Button` (CVA) provides the shared button abstraction with three variants
+3. **Composite layer**: `ConfirmButton` and `OverflowMenu` wrap `Button` with additional behavior
+4. **Usage layer**: Components use either `Button` component or raw `<button>` elements with inline Tailwind classes
+
+The `cn()` utility from `lib/utils.ts` is used in 9+ components for conditional class merging.
+
+Custom animations are defined in `index.css` via `@keyframes` + `@utility` pairs: slide-in-right, confirm-pulse, settle-to-bottom, rise-to-center, slide-down-in, slide-up-out, concentration-pulse.
+
+## Open Questions
+
+1. The `hover-action` and `hover-action-bg` tokens are defined but rarely used — `hover-action` appears only once in `action-bar.tsx:565`. Is this intentional or an incomplete migration?
+2. The `accent` color (`#3b82f6`) is identical to `primary` — are they intended to diverge in the future, or is this redundancy?
+3. Should the hardcoded HP adjust colors (red/emerald) be promoted to theme tokens (e.g., `hover-damage`, `hover-heal`)?
