/* web/brand.css -- Rutken shared design system (2026-10).
 *
 * The single source of visual truth for the marketing + docs + blog site:
 * tokens, base elements, and the shared components (nav, buttons, cards,
 * hero, sections, footer). index.html / login.html / docs.html / blog.html
 * all include THIS file first, then only page-specific styles on top. Do not
 * fork the palette or the type scale per page -- extend here.
 *
 * Brand: orange accent carried over from the GUI (crates/gui) --
 * ACCENT #e0843a, ACCENT_BRIGHT #ec9d55, ACCENT_SOFT #f5be8a -- on a deep,
 * technical dark surface. Serious, fast, offensive-and-defensive security
 * tooling; the design should read confident and engineered, never playful.
 *
 * Shared components (all additive -- nothing here is renamed/removed, so the
 * home / login / docs / blog pages keep working byte-for-byte):
 *   .container .btn .card .surface .grid .badge .eyebrow        (layout kit)
 *   .site-header .site-footer .brand                            (chrome)
 *   .terminal (+ .term-*, .chip high|medium|low)               (NEW: console hero)
 *   .stat-strip / .stat                                        (NEW: perf band)

 * Progressive enhancement: motion.js adds `.motion` to <html> ONLY when the

 * gated on BOTH `.motion` AND `prefers-reduced-motion: no-preference`, so with
 * JS disabled, motion.js missing/failed, or reduced motion requested, nothing
 * is ever hidden — each element renders in its final, visible state. We animate
 * only transform/opacity (GPU-friendly) and keep will-change scoped to the
 * reveal targets. The global `@media (prefers-reduced-motion: reduce)` rule
