Implement the 028-semantic-hover-tokens feature that unifies hover colors across all interactive UI components via six CSS custom property tokens (three text, three background) defined in the Tailwind v4 theme, replacing hardcoded hover classes in 9 component files plus the shared Button primitive with semantic token references so all hover colors can be globally reconfigured from one place

+# Specification Quality Checklist: Semantic Hover Tokens
+
+**Purpose**: Validate specification completeness and quality before proceeding to planning
+**Created**: 2026-03-10
+**Feature**: [spec.md](../spec.md)
+
+## Content Quality
+
+- [x] No implementation details (languages, frameworks, APIs)
+- [x] Focused on user value and business needs
+- [x] Written for non-technical stakeholders
+- [x] All mandatory sections completed
+
+## Requirement Completeness
+
+- [x] No [NEEDS CLARIFICATION] markers remain
+- [x] Requirements are testable and unambiguous
+- [x] Success criteria are measurable
+- [x] Success criteria are technology-agnostic (no implementation details)
+- [x] All acceptance scenarios are defined
+- [x] Edge cases are identified
+- [x] Scope is clearly bounded
+- [x] Dependencies and assumptions identified
+
+## Feature Readiness
+
+- [x] All functional requirements have clear acceptance criteria
+- [x] User scenarios cover primary flows
+- [x] Feature meets measurable outcomes defined in Success Criteria
+- [x] No implementation details leak into specification
+
+## Notes
+
+- All items pass. Spec is ready for `/speckit.clarify` or `/speckit.plan`.
+- The spec references "CSS custom properties" and "theme file" which are borderline implementation — however these are part of the user's original description and represent the feature's domain language, not specific technology choices.
