/**
 * ZynoStack Workroom.
 *
 * ── THE TOKENS ARE ZYNOSTACK'S, NOT THE CATALOGUE'S ─────────────────────────
 *
 * Digital Umbrella's products are dark and blue. This is a ZynoStack tool: warm
 * paper, one brass accent, near-black ink. Four fixed values were given, accent
 * #c97a00, ink #15171a, paper #fdfcf8, background #f1ede4, and everything else
 * below is derived from them and then MEASURED. No value here was chosen by
 * eye.
 *
 * ── EVERY RATIO, COMPUTED ───────────────────────────────────────────────────
 *
 * WCAG 2.1 contrast, by `tests/web-design.test.js`, which recomputes each pair
 * from this file and fails the build if one drops. Floors: 4.5 for text of any
 * size (the product uses no large-text exemption), 3.0 for a control boundary
 * or a focus ring.
 *
 *   TEXT                       on --paper   on --bg   on --surface
 *   --ink        #15171a          17.49       15.37       14.29
 *   --ink-2      #4a4f57           8.03        7.06        6.56
 *   --ink-3      #5c6167           6.09        5.35        4.97
 *   --accent-ink #8a5400           6.11        5.37        4.99
 *   --good       #17673a           6.73        5.92        5.50
 *   --warn       #8a5a00           5.77        5.07        4.72
 *   --bad        #a01a12           7.72        6.78        6.30
 *
 *   TEXT ON A TINTED CHIP      --accent-tint  --good-tint  --warn-tint  --bad-tint
 *   --ink        #15171a           14.63        15.16        15.20        13.94
 *   its own ink (accent/good/warn/bad)
 *                                   5.11         5.83         5.02         6.15
 *
 *   CONTROL BOUNDARIES AND THE RING (floor 3.0)
 *   --edge  #7f7a6d on --paper 4.17, --bg 3.66, --surface 3.40,
 *                   --accent-tint 3.49, --good-tint 3.61, --warn-tint 3.62,
 *                   --bad-tint 3.32 (the lowest of the seven)
 *   --ring  #8a5400 on --paper 6.11, --bg 5.37, --surface 4.94
 *   --accent-deep #a06100, the border of a filled accent button,
 *                   on --paper 4.87, --bg 4.27, --surface 3.97
 *
 *   FILLS
 *   --ink on --accent 5.36   |   --paper on --ink 17.49
 *
 * TWO VALUES THAT ARE DELIBERATELY NOT USED AS TEXT:
 *
 *   --accent #c97a00 measures 3.26 on paper and 2.87 on the background. It is a
 *   FILL, a rule and a bar, never a letter. Accent-coloured text is
 *   --accent-ink. This is the one mistake this palette invites, and the design
 *   check fails on `color:var(--accent)`.
 *
 *   --line #ded8c9 measures 1.38. It separates regions and MUST NOT border an
 *   interactive control, which needs 3.0: that is --edge. Five of the ten live
 *   accessibility failures in the catalogue were this one confusion.
 *
 * SURFACE SEPARATION is the weak point of a warm-paper palette and is stated
 * rather than hidden: --bg to --paper is only 1.138 and --bg to --surface
 * 1.076. Neither reads as a boundary on its own, so every card, column and
 * panel also draws a 1px --line rule. Remove the rule and the layout dissolves.
 *
 * No external resource of any kind: no font file, no icon set, no image. The
 * page's own Content-Security-Policy allows none, so anything added here that
 * fetches would fail silently rather than 404 visibly.
