/*
 * hc-control-plane-ui — Hypernym Design System (HDS) retrofit.
 *
 * Tokens come from .claude/skills/hypernym-design/colors_and_type.css,
 * mirrored into ./hds-tokens.css as the build's single source of
 * truth. When HDS evolves, swap hds-tokens.css and re-build — this
 * file consumes only the canonical --bg-*, --fg-*, --hot-*, --cool-*,
 * --font-*, --tr-*, --sp-*, --r-* variables.
 *
 * Anti-slop discipline (per CLAUDE.md + HDS README):
 *   - NO off-brand cool shades (single hot/cool axis only — see HDS README)
 *   - NO gradient text except on the ONE hero treatment
 *   - NO emoji icons (HDS reserves emoji for GeoCities pastiche only)
 *   - NO rounded cards with colored left-border accents
 *   - SF Pro Display -> Inter fallback chain via --font-sans
 *   - Section heads ALL CAPS with letter-spacing (the brand signature)
 *   - The brand is mostly square: radius only on inputs (--r-lg) and
 *     the logo crop (--r-md).
