+# Task: Add frontend style system baseline
+
+## Goal
+
+Remove app-shell styling drift by routing shared chrome controls through Vuetify components and centralized theme-backed tokens.
+
+## Scope
+
+- Expose reusable CSS variables backed by the Vuetify theme.
+- Add shared app-shell primitives for navigation buttons, icon buttons, popovers, and menu items.
+- Replace native shell buttons with Vuetify controls in `App.vue`, `AppBar`, `AppSidebar`, `SidebarUserMenu`, and `WorkspaceSelector`.
+- Leave feature-screen native button migration to a follow-up task because it crosses many workflows.
+
+## Validation
+
+```bash
+cd frontend
+npm run build
+```
+
+## Done
+
+- [x] Tailwind preflight loads before Vuetify styles.
+- [x] App-owned CSS loads after Vuetify styles.
+- [x] Shared Vuetify defaults are centralized.
+- [x] Legacy global native button/card selectors were removed.
+- [x] App-shell styles use shared theme-backed tokens.

+# Task: Replace native feature buttons with Vuetify controls
+
+## Goal
+
+Move remaining interactive feature-screen buttons from native `<button>` elements to Vuetify controls so button styling consistently flows through Vuetify.
+
+## Scope
+
+- Replace action buttons with `v-btn`.
+- Replace icon-only buttons with `v-btn` using icon-sized styling.
+- Preserve specialized non-button native controls only when Vuetify would reduce capability, such as file inputs.
+- Keep behavior unchanged while converting one feature area at a time.
+
+## Likely Files
+
+- `frontend/src/components/ImageCropperDialog.vue`
+- `frontend/src/features/**/**/*.vue`
+- `frontend/src/static/**/*.vue`
+
+## Validation
+
+```bash
+cd frontend
+npm run build
+```
+
+## Done
+
+- [x] Native `<button>` elements under `frontend/src/**/*.vue` were migrated to `v-btn`.
+- [x] Public SSR rendering installs the shared Vuetify plugin.
+- [x] Frontend build and public prerender pass.
