/*
 * Instance section design language (.ins-*) — store.createrun.com /instance pages.
 *
 * Concept: "Control Room" — a full-bleed deep-ink hero band anchored on an
 * oversized glass terminal (the one-line install IS the product promise),
 * followed by a calm light "paper" zone with crisp white cards and a mono
 * label vernacular (eyebrows, chips, checksums).
 *
 * Contract classes consumed by Pages/Instance/* and js/instance.js states
 * (.is-active / .is-copied / [hidden]) — do not rename.
 * Tables intentionally have no styles here: use cr-tables.css.
 *
 * Redesigned 2026-07-25 (screenshot-iteration pass); replaces the first-wave
 * token-only sheet after founder design review. The hero band is deliberately
 * dark in both themes; the light zone uses fixed "paper" values, so this
 * section does not re-skin under [data-cr-theme="dark"] (the Store never
 * toggles it — Editor-only mechanism).
