/*!
 * SDA Theme Master (CSS) v2
 * ---------------------------------------------------------------------------
 * Named themes and component colors are defined here. theme-master.js selects a
 * theme (data-theme / data-theme-colors / data-theme-mode on <html> and <body>)
 * and supplies optional user color inputs (--sda-user-*, --on-primary).
 *
 * Structure
 *   1. Base tokens + mode tokens (dark / light)
 *   2. Theme palettes             (one small block per theme, raw colors only)
 *   3. Derived public tokens      (--bg-color, --primary-color, ... + helpers)
 *   4. Page polish                (selection, scrollbars, focus, transitions)
 *   5. Role map + utility bridges (data-theme-role, Tailwind hex remaps)
 *   6. Shared components          (glass, aura glow, monetization)
 *   7. Light-mode component rules (every light theme, token-driven)
 *   8. Dark-mode component rules  9. .sda-* component library
 *  10. Print / contrast / responsive  11. Per-theme signatures
 *  12-16. Design tokens, layout + type utilities, a11y, motion, mobile
 *
 * Requires CSS color-mix() and CSS nesting (all current evergreen browsers).
