Add jsinspect-plus (AST-based structural duplication detector) to pnpm check with threshold 50 / min 3 instances. Fix all findings: - Extract condition icon/color maps to shared condition-styles.ts - Extract useClickOutside hook (5 components) - Extract dispatchAction + resolveAndRename in use-encounter - Extract runEncounterAction in application layer (13 use cases) - Extract findCombatant helper in domain (9 functions) - Extract TraitSection in stat-block (4 trait rendering blocks) - Extract DialogHeader in dialog.tsx (4 dialogs) Net result: -263 lines across 40 files.

Add rules covering bug prevention (noLeakedRender, noFloatingPromises, noImportCycles, noReactForwardRef), security (noScriptUrl, noAlert), performance (noAwaitInLoops, useTopLevelRegex), and code style (noNestedTernary, useGlobalThis, useNullishCoalescing, useSortedClasses, plus ~40 more). Fix all violations: extract top-level regex constants, guard React && renders with boolean coercion, refactor nested ternaries, replace window with globalThis, sort Tailwind classes, and introduce expectDomainError test helper to eliminate conditional expects.
