/* D&D Suite — base + auth CSS foundation (SPEC §8 / §8a / §11).
 *
 * The extracted brand foundation: dark palette as CSS variables, the Marcellus/Spectral
 * type system, a small reset. Enough for base + login to look on-brand; the full
 * character-sheet CSS (sheet.css) is a later chunk.
 *
 * Fonts are SELF-HOSTED (CSP font-src 'self'): @font-face points at /static/fonts/. The
 * actual font binaries land in a later chunk; until then a robust serif/old-style fallback
 * keeps the look on-brand. No Google CDN, no inline styles (style-src 'self'). */
