/* SHELEG Design — Showroom token layer (product-led companies whose best
   argument is the product on screen).
   Copy verbatim; consume only var(--…) in components.

   The page is a white gallery and the product is the exhibit. One specimen per
   page, at real size, under the seven-layer shadow; everything else stays quiet
   so the specimen reads as evidence rather than decoration.

   Extracted from https://attio.com/ on 2026-08-09 by reading its live computed
   styles. The reference declares its palette in CIE Lab, which this repository's
   palette gate cannot parse — every value below was converted by painting the
   declared lab() into a 1x1 canvas and reading the sRGB bytes back, so the hex
   is the browser's own conversion rather than arithmetic of ours. Ratios were
   computed by importing test/validate_palette.py.

   One correction, in CONTRAST. */

     sees changes — what changes is that re-tinting --accent re-tints the ring,
     where before it kept the old blue silently (board B-023/B-024).

     CORRECTED 2026-08-20. This used to keep the relative form as a SECOND
     declaration here and called the literal above it a fallback: "a browser that
     does not parse the second line keeps the first". That is true of an ordinary
     property and FALSE of a custom property. `--x: rgb(from …)` parses anywhere —
     a custom property accepts almost any token sequence — so it wins the cascade
     everywhere, and the invalidity surfaces only where it is substituted, as
     invalid-at-computed-value-time. At that point the literal is long gone and
     `var(--ring-focus)` resolves to `unset`: an INVISIBLE FOCUS RING, on the one
     degradation this pack says it may not ship. The derived form lives in the
     `@supports` block at the end of this file, which is the mechanism that
     actually guards it. */
