/*
 * hesskey-band.css — the unified brand band (extracted from the web-app's
 * approved Private redesign, 2026-06-12). Shared by /web-app/ and /foundation/
 * so the two can't drift (one source of truth, like hesskey-nav's TABS).
 *
 * Per-page accent: set --band-color (band background) and --band-ink (the
 * active-tab pill's text) on :root. Defaults reproduce the web-app's green
 * exactly, so a page that sets nothing looks identical to before:
 *
 *   /web-app/   → green   (defaults; no override needed)
 *   /foundation/→ purple  (:root { --band-color:#7B1FA2; --band-ink:#6A1B9A })
 *
 * Requires hesskey-app-theme.css (the --app-* tokens) loaded first, and
 * body.authed to reveal the band + its controls.
