  /* Brand palette — approved red direction (CMS sign-off, Jul 2026).
     These values match the Comera brand kit's tokens exactly
     (final-kit/tokens/tokens.css): --tpm-accent → --pulse, --tpm-accent-ink →
     --pulse-deep, --tpm-accent-on-dark → --pulse-light, --tpm-accent-2 → --red-deep,
     --tpm-dark → --ink, --tpm-light → --chart. The kit is the authority; if it changes,
     change these. (They were originally derived from the logo artwork before the kit's
     colour side was regenerated, and turned out identical.)

     The previous direction had TWO accents (teal + orange). The approved brand has ONE
     (red), so --pulse and --signal now resolve to the same red; both names are kept
     because they still carry distinct SEMANTIC roles in the stylesheet (informational
     accent vs. call-to-action) and may diverge again later.

     Three reds, because one can't cover every surface at AA contrast:
       --pulse        brand red. Backgrounds, borders, graphics, large text. On white it
                      is 4.37:1 — fine for large/UI, NOT for small body text.
       --pulse-deep   darker red for SMALL text on light surfaces (7.01:1 on white).
       --pulse-light  the logo's own mid tint, for accent text on DARK surfaces
                      (6.02:1 on ink) where the full-strength red only reaches 4.14:1. */
