/*
 * brand.core.css — the shared warm ground: the --role-* names every room
 * declares, with the house's own values as the reference implementation.
 * Ground values sit in obligente's committed warm family (#FBF7F0 paper,
 * #241D16 ink); state tints adopt purser's reviewed studio pairs.
 *
 * --role-accent and --role-focus are DECLARED in core.tokens.json and VALUED
 * only in a room file — a room that forgets its accent fails parity
 * (ACCENT_UNSET) rather than silently inheriting someone else's identity.
 *
 * Warm throughout: no #FFF, no #000, no pure grey. check-contrast.mjs
 * asserts non-zero chroma on every ground and ink.
 *
 * Governed pair registry — check-contrast.mjs PARSES this block (purser's
 * T600 mechanism); the list is never typed twice:
 *   pair: --role-ink on --role-ground
 *   pair: --role-ink on --role-ground-raised
 *   pair: --role-ink on --role-ground-sunk
 *   pair: --role-ink-muted on --role-ground
 *   pair: --role-ink-muted on --role-ground-raised
 *   pair: --role-ink-faint on --role-ground
 *   pair: --role-line-strong on --role-ground @3
 *   pair: --role-line-strong on --role-ground-raised @3
 *   pair: --role-state-neutral-ink on --role-state-neutral
 *   pair: --role-state-active-ink on --role-state-active
 *   pair: --role-state-pending-ink on --role-state-pending
 *   pair: --role-state-verified-ink on --role-state-verified
 *   pair: --role-state-blocked-ink on --role-state-blocked
 *   pair: --role-state-danger-ink on --role-state-danger
