   Duravex — site styles

   The design system below is ported from the Duravex line card, the page
   management approved. It was written as a self-contained fragment pasted
   into Drupal, with all CSS inline and every class scoped under `.dvx` to
   survive DXPR. None of that is needed here: the scoping wrapper is gone,
   classes are unprefixed, and the styles live in this file.

   ⚠ PALETTE DIVERGENCE — see docs/branding.md.
   These are the line card's values, not the branding PDF's. They are close
   but not identical, and --zinc has no equivalent in the guidelines at all.
   Kept as-is so the approved design is preserved; the reconciliation is an
   open decision, not an oversight.

/* ==========================================================================
   Dark bands

   Any band sitting on --ink or --brand. This block comes LAST on purpose:
   several components set a dark text colour for use on light backgrounds
   (.lede, .sec-head p, .card p), and those rules have the same specificity
   as a `.hero--dark .lede`-style override. Source order is what decides it,
   so the dark rules must come after every component that sets a colour.

   Rules:
     - body copy is white, never a tinted grey
     - eyebrows and small accents are gold
     - mono labels use a light tint, still ≥ 10:1 on ink
