+})
+```
+
+## Notas
+
+Layout inteligente: los KPIs se ajustan automáticamente a 2/3/4 columnas según cantidad. Los charts soportan span para ancho completo.

+El porcentaje se clampea a [0, 100] internamente. El buffer se renderiza como capa semitransparente detrás del fill.

+- `progress-stripes`: background-position de 0 a 1rem
+- `progress-indeterminate`: translateX de -100% a 300%

+<ThemeProvider themes={allThemes} defaultTheme="dark">
+  <App />
+</ThemeProvider>
+
+// Dentro de un componente:
+function ThemeSwitcher() {

+    </select>
+  )
+}
+```
+
+## Notas
+
+Detecta prefers-color-scheme automáticamente. Persiste elección en localStorage. Exporta ThemeProvider (componente) y useTheme (hook).

+## Notas

+Exporta 5 subcomponentes: TooltipProvider, Tooltip, TooltipTrigger, TooltipPortal, TooltipContent.
+TooltipProvider gestiona el delay global — envolver la app o sección con un único Provider.
+TooltipContent incluye Arrow con fill-primary automático.
+Depende de @base-ui/react — asegurarse de que está en package.json del frontend.

+- DPR automático: escala el canvas al devicePixelRatio de la pantalla
+- Resize automático: detecta cambios de tamaño via getBoundingClientRect
+- Throttle configurable: rAF corre a ~144fps nativo, el hook filtra a N fps
+- FPS real: `renderFpsRef.current` tiene los FPS medidos (no el target)
+- drawRef pattern: actualiza el callback sin re-crear el loop de animación

+`mutate()` es fire-and-forget, `mutateAsync()` retorna Promise. Estado: idle → loading → success/error.

+## Notas
+
+Sin provider, los hooks hacen fallback al singleton `wailsCache`. El provider solo es necesario para cache custom o opciones globales.

+- `VariantProps<V>` — re-exportado de `class-variance-authority`. Extrae el tipo de props de un `cva()` call.
+- `ComponentBaseProps` — props comunes a todos los componentes: `className` y `children` opcionales.
+- `PropsWithVariants<V>` — combinación de `ComponentBaseProps` con las variantes de un `cva()` concreto. Usar como base para las props de cualquier componente con variantes.
+
+## Uso
+
+```typescript
+import { cva } from "class-variance-authority"
+import { type PropsWithVariants } from "@/types/core/component_variants"
+
+const buttonVariants = cva("base-classes", {
+  variants: { size: { sm: "...", md: "..." } }
+})
+
+type ButtonProps = PropsWithVariants<typeof buttonVariants>
+```
+
+## Notas
+
+Requiere `class-variance-authority` como dependencia del proyecto consumidor. `React.ReactNode` requiere que `react` esté en el scope — en proyectos con `@types/react` esto se resuelve automáticamente.
