+# Task 050 - Selector Popover Tailwind Refactor
+
+## Goal
+Bring `ModelSelector` and `OpencodeBinarySelector` popovers in line with the design tokens, eliminating manual light/dark class stacks.
+
+## Prerequisites
+- Task 049 complete (dropdown utility helpers ready).
+
+## Acceptance Criteria
+- [ ] `src/components/model-selector.tsx` and `src/components/opencode-binary-selector.tsx` use token-backed utilities for surfaces, borders, focus rings, and typography.
+- [ ] Shared selector utilities live in `src/styles/components.css` (e.g., `.selector-trigger`, `.selector-option`, `.selector-section`).
+- [ ] All `dark:bg-gray-*` / `text-gray-*` combinations are removed in favor of tokens or newly added utilities.
+- [ ] Combobox states (highlighted, selected, disabled) and validation overlays preserve current UX.
+
+## Steps
+1. Map all class usages in both selectors, noting duplicated patterns (trigger button, list items, badges).
+2. Create selector-specific helpers in `components.css` that rely on tokens.
+3. Update component markup to use the helpers and Tailwind utility additions.
+4. Verify validation/binary version chips and search input styling in both themes.
+
+## Testing Checklist
+- [ ] Run `npm run build`.
+- [ ] In dev mode, open the selector popovers, search, and select options to confirm styling and focus rings.
+
+## Dependencies
+- Depends on Task 049 dropdown helpers.
+- Blocks folder selection advanced settings refactor.
+
+## Estimated Time
+1.0 hour
+
+## Notes
+- Branch suggestion: `feature/task-050-selector-popover-refactor`.
+- Document any intentional color tweaks in the PR if tokens reveal contrast issues.
