/* ---------------------------------------------------------------------------
 * keywords.css — page-specific styles for the Keywords template
 * ---------------------------------------------------------------------------
 * Extracted from the former inline <style>${pageStyles}</style> block in
 * templates/keywords.ts (App-Building Bible principle 5). The brand-token
 * interpolations (${brand.*}) are resolved here to their literal values, which
 * are the single source of truth in templates/layout.ts:
 *   primary #4951EF  primaryLight #EEEFFE  bg #F9FAFB  surface #FFFFFF
 *   ink #09090B  muted #71717A  border #E4E4E7  borderLight #F4F4F5
 *   radiusCard 16px  radiusSmall 12px  radiusInput 10px
 *   fontMono 'JetBrains Mono','SF Mono','Cascadia Code',monospace
 *
 * Modal/toast visibility toggles via the `visible` class (added by the client
 * module); dynamic difficulty-bar width/colour move to CSS custom properties
 * set from data-* attributes (principle 17).
