/* NASJ — Color tokens  ·  v3 LOCKED: ink + thread-EVENT
 *
 * The environment is a reading room: warm paper ground, near-black ink, and a
 * muted stone for English annotation. THERE IS NO STANDING ACCENT COLOUR.
 *
 * 98% ink on paper. The single madder weft — `--thread-event` (#B23A1A) — is an
 * EVENT, not a property: it is painted only at the moment of connection in the
 * loom (one weft thread + its knot), and NOWHERE else. Words, numbers, dividers,
 * active states, links, hover, focus, email — all ink.
 *
 * The old earthen accent (#8D5C4B) is RETIRED. `--thread` and every accent alias
 * now resolve to ink, so any consumer that still reads var(--thread) (Badge,
 * Card top-rule, PullQuote, ThreadDivider, Tabs underline, form focus, Switch…)
 * renders ink automatically. To use the event red, reference --thread-event
 * explicitly on the single loom mark; to defer colour entirely, override
 * --thread-event: var(--ink) on the page root (pure mono).
