/* ============================================================================
   ASYMCHEM BRAND LAYER — hand-authored, loaded AFTER css/asymchem.css.
   asymchem.css is REGENERATED by site-factory/generate-identity.js, so nothing
   here may live in that file (site-factory/SCAFFOLD-RUNBOOK.md §2 / §9.3).

   Direction: the real Asymchem mark is an open navy hexagon "C" beside a wide,
   squared industrial wordmark, printed in deep navy #040348 over near-black ink
   #231815 on white. So the site is built as a CDMO datasheet: near-neutral cool
   white grounds, navy structure lines, square corners, mono micro-labels, and a
   hexagon motif that repeats the mark. No decorative colour beyond the brand
   navy and one teal data accent.

   Contrast rule followed throughout (§9.4): tokens are only ever DARKENED on
   light grounds; nothing here changes a colour that renders on the footer ink
   ground, the sale ribbon, or a photo scrim.
   ============================================================================ */

       The generated ramp tints every neutral with the primary's hue at 28%

       brand's white/navy/ink palette. Pull the light end back to a near-neutral
       cool grey; the dark end keeps a trace of navy so ink still feels branded. */

   The same applies to --primary-lighter (#2623c1): it is a legible link colour
