/* developments/css/headroom.css — Headroom v1 (#1191).
 * Styles for the gated "Zoning Headroom" rail surface (control panel + per-zone
 * legend) and its rail icon. Reuses the .panel / .panel-head / .dev-explore-body
 * shell from dev.css; everything here is .dev-headroom-* scoped (no bleed).
 * Token vars carry conservative fallbacks so the panel reads correctly even if a
 * token is renamed. */
