 ### AD-2: Theme = Aura preset, Crewli teal primary, dark mode preserved
 
-The Aura preset is configured via `@primevue/themes` `definePreset(Aura, { semantic: { primary: { ... } } })`. The Crewli teal (`#0D9394` light, `#0B7F80` dark) maps to `primary.500` and `primary.600` semantic tokens. Surface, success, info, warning, error tokens use Aura defaults unless explicit Crewli equivalents exist. Dark mode is wired via PrimeVue's `darkModeSelector: '.dark'` config, integrated with the existing `@core/composable/useSkins.ts` until F6 cleanup.

Same maintainers, same API surface (Aura preset, `definePreset`, semantic tokens). F3 commit B1 installed `@primeuix/themes@^2` directly; this paragraph and Appendix B are aligned with that ecosystem state.
 
 **Per-tenant overrides:** primary color and logo only (per project-level decision). Implementation: a Pinia computed reads `useOrganisationStore().branding.primaryColor` and patches the active preset via `usePrimeVue().config.theme.preset` at organisation-switch time. Full white-labeling is explicitly out of scope.

 ### AD-5: Icons = Iconify-Tabler retained, PrimeIcons not installed
 
-The 593 `tabler-*` icon references in templates remain unchanged. PrimeVue's components accept any element in icon slots and `:icon` props can render arbitrary class names. The custom Vuetify icon component in `apps/app/src/plugins/vuetify/icons.ts` is replaced by a tiny generic `<Icon>` component that renders `<i :class="...">` for Iconify class strings — or, where call-sites already use `<VIcon icon="tabler-X">`, the migration substitutes `<i class="iconify tabler-X">` directly. The 5 SVG checkbox/radio overrides in `@images/svg/` become unused (PrimeVue's Checkbox/RadioButton ship their own styling) and are deleted in F6.
+The 593 `tabler-*` icon references in templates remain unchanged. PrimeVue's components accept any element in icon slots and `:icon` props can render arbitrary content. The custom Vuetify icon adapter in `apps/app/src/plugins/vuetify/icons.ts` is replaced by a tiny generic `<Icon>` component (at `apps/app/src/components/Icon.vue`) that wraps `@iconify/vue`'s `<Icon>` component and emits real `<svg>` markup. Call-site migration substitutes `<VIcon icon="tabler-X" />` with `<Icon name="tabler-X" />`.

+
+> **Drift correction (F3 B9):** RFC v1.0 described the new `<Icon>` component as rendering `<i :class="i-tabler-X">` utility classes. That approach would require UnoCSS to resolve `i-tabler-*` into real icon output, and UnoCSS is not in the Crewli stack — the project already uses `@iconify/vue` (installed at 4.1.2) for SVG icon rendering through Vuetify's icon adapter. F3 commit B6 implements `Icon.vue` as a thin wrapper around `@iconify/vue` accordingly. The substitution preserves existing icon naming (`tabler-eye`, `tabler-user`, etc.) and produces equivalent SVG output to the current Vuetify path. UnoCSS-style utility-class icon rendering was considered but not adopted; the wrapper retains Crewli's continuity.
 
 **Rationale:** Throwing away 593 icon references is needless cost; PrimeVue does not require its own icon set; the project's Tabler aesthetic is preserved.
