/**
 * theme.css — GetXtra Tools brand design system (FRESH REBUILD)
 * =========================================================================
 * Palette: RED · BLACK · WHITE.
 *   - Red   (#e11captured as --brand) = primary action / accent / highlight
 *   - Black (#0a0a0a)                 = text (light mode) & surfaces (dark)
 *   - White (#ffffff)                 = surfaces (light) & text (dark)
 *
 * 100% original, self-written. No third-party CSS, no CDN, no downloaded
 * fonts (native system stack). This file layers a token-driven component
 * system on top of the freshly generated utility framework
 * (custom-utilities.css, whose `primary-*` scale is also red).
 *
 * Sections:
 *   1. Design tokens (+ dark remap)
 *   2. Base reset / typography / scrollbar / focus
 *   3. Buttons
 *   4. Cards
 *   5. Forms
 *   6. Badges
 *   7. Alerts
 *   8. Tables
 *   9. Modal / dropdown
 *  10. Brand helpers (gradient text, glass-card->solid, animations)
