## Changesets

### Minor Changes

- Brand themes and brand slot.
  
  - `caThemeHandle(options)` and `caThemePlugin(options)` accept `ThemeOptions`: `defaultPreset`, `defaultScheme` and `presets`, brand presets generated from one hex color and inlined in `<head>`. Before this, the init script always fell back to `amber`/`dark` and overrode `data-preset` set in `app.html`.
  - `colorScheme` starts from the configured defaults instead of hardcoded `amber`/`dark`.
  - `PresetId` accepts custom ids; `BuiltinPresetId` lists the eight shipped presets.
  - Charts use the brand hex as the first series color for brand presets (they fell back to amber).
  - `hexToOklch` and `brandPresetCSS`/`themeHead`/`themeScript` exported for custom setups.
  - `tokensToCSS` dark block now includes the neutral outline/glass/scrim tokens, so generated presets no longer inherit light-mode outlines in dark mode.
  - `AuthLayout` panel mixes brand with neutrals in OKLab: in OKLCH the hue swung toward 0° (blue brands rendered purple).
  - `AuthLayout` brand panel now hides below 768px (the override lost to the scoped rule); `AuthCard` footer links use the brand color.
  - `ThemeToggle`: light/dark button for the AppShell rail, SSR-safe icon.
  - `brand` snippet for the logo in `AppShellLayout` (top of the Rail and mobile header; `MobileHeader` gains `leading`) and in `AuthLayout`. Both default to the previous "CA" text mark.
