 * ============================================================================
 * "HUD" theme - ported from 174bg/manager/public/theme.css so the two
 * 174bg sites (manager.174bg.net and handbook.174bg.net) share a look: a
 * near-black backdrop with a faint accent grid + radial glow, Sora
 * headings/body text, Bai Jamjuree nav/button chrome, and glassy
 * accent-bordered panels. Manager has no light mode at all, so this is
 * applied unconditionally (see `appearance: "force-dark"` in config.mts)
 * rather than scoped to `.dark`.
 *
 * 2026-07-13: retinted + refonted to align with robertsspaceindustries.com's
 * own design tokens (see .gitignored/context.dev/style-guides/
 * robertspaceindustries.com.json, exported from a CSS Stats scan of the live
 * site) - a single blue accent (#54adf7) on true black in place of the
 * earlier arbitrary navy/cyan pairing, Sora/Bai Jamjuree in place of
 * Orbitron/Rajdhani, flat slate-bordered "card" panels in place of
 * glass-blur ones, and heading sizes/weights/link treatment matched to
 * RSI's own type scale.
