+Actualizacion Eidos 2026-05-16:
+
+- Primera pasada de componentes Option C ejecutada:
+  - Barrels multi-part normalizados a asignacion explicita per-property
+    (`const Drawer = DrawerRoot as DrawerNamespace; Drawer.Trigger = Trigger;`)
+    y sin `Object.assign`.
+  - Tipos root visuales renombrados a `AccordionProps`, `DrawerProps`,
+    `DialogProps`, `TabsProps`, etc. Eidos ya no define `XxxProviderProps`;
+    `ProviderProps` solo aparece como alias importado desde Soma cuando la
+    superficie headless lo llama asi.
+  - `src/uix/eidos/components/README.md` actualizado con la convencion real.
+  - `Toaster` deja de usar un alias interno `Provider` para no reintroducir el
+    modelo mental retirado.
+  - Aniadido `src/uix/eidos/lib/style.ts` con `composeInlineStyle(...)` y
+    aplicado a wrappers que mezclan estilo del consumidor con custom properties
+    de receta: overlay de Dialog/Drawer, Toast.Viewport, Checkbox.Group,
+    RadioGroup, Tabs.Indicator, Icon y primitives SVG.
+- Validacion de esta pasada:
+  - `npm run check` -> 0 errores, 0 warnings.
+  - `npx vitest run src/uix/eidos` -> 4 archivos, 56 tests OK.
+  - `npm run test` -> 233 archivos, 2270 tests OK.
+  - SSR smoke de `web/routes/uix/components/{accordion,avatar,checkbox,
+    collapsible,dialog,drawer,popover,radio-group,switch,tabs,toast,toggle,
+    tooltip}` -> HTTP 200.
+- Siguiente foco recomendado en Eidos:
+  1. Auditar recipes/CSS contra tokens generados por `ActiveEidos` y decidir
+     que CSS legacy queda como recipe por componente y que debe generarse.
+  2. Revisar componentes visuales que anaden partes eidos-only (`Header`,
+     `Footer`, `Status`, `Main`, SVG primitives) para documentar si necesitan
+     morfo propio o si son recipe primitives privadas.
+  3. Revisar tests de componentes Eidos: hoy hay cobertura del runtime Eidos,
+     pero no tests unitarios especificos para wrappers visuales.
