/* ========================================
   WORK PAGE — Vanini Space Portfolio Grid (brown/pink)
   vanini.space
   ======================================== */

/* ============ DESIGN LANGUAGE OVERRIDE ============
   matrix.css is still loaded (for its shared structural chrome — .top-nav,
   .nav-tab, .ipod-*, .glitch-* — this page has never had its own copy of
   that layout CSS, only colour retints on top of it; dropping matrix.css
   entirely broke all of it, see the style-guide-audit follow-up note dated
   2026-08-14). tokens.css now loads alongside it — different variable
   names, no collision — so this :root block below can override matrix.css's
   own green :root values with ones DERIVED from tokens.css, instead of the
   hardcoded, off-palette duplicates that used to sit here (style-guide
   audit S1/S2). Names are kept as-is (--matrix-green legitimately holds
   pink now, not renamed to something like --accent) to avoid a blind
   rename across every call site in this file; that's a real but separate,
   higher-risk follow-up from fixing the values themselves.
   --mag itself is a FILL colour and fails text contrast on this ground
   (2.8:1) — --mag-tint is tokens.css's accessible reading of the same hue
   for text (9.2:1), see tokens.css for the reasoning.
   --font-display is the SINGLE swap point for the planned Anton -> Panchang
   change: once Panchang is self-hosted, edit only the line below. */

   read in --sans (Inter), not matrix.css's --font-mono. Same specificity as
   matrix.css's body rule, source order wins since this file loads after it. */

   rather than editing the shared file. Values match the source rule's blur
   radius / alpha exactly; only the RGB triplet changes. */

/* ============ BACKGROUND ART ============ */
/* Disabled: the background is now the site-wide video (see site-shell.css).
   This layer was tuned as `screen` at 6% over an opaque #0a0a0a body. With
   the body transparent it blends against the footage instead, and the
   reference image reads as a second, competing picture rather than a
   texture — verified in the browser, not assumed.

   The デザイン No. 155 reference now drives the enter screen's structure and
   palette, which is a better use of it than a wash on this page.

   Re-enable only by re-tuning against the video; restoring these values as
   they were will reproduce the same clash. */
