   ROYCE CAPITALS — market page header
   File: css/market-header.css   (the six market pages only)

   Ported September 2026 from update/marketHeaders/component/css/
   royce-market-header.css. One compact navy band under the fixed bar: gold
   eyebrow + headline in one H1, a paragraph, Start Trading, a View instruments
   anchor, and a per-market inline SVG artwork on the inline-end side, closed by
   a 1px gold hairline. Everything is scoped under .rmh.

   What changed in the port, and why:
   - Fonts inherit Ping AR + LT. The package set Marcellus/Inter, which were
     never shipped here (NFR-10).
   - Tokens come from css/royce-header.css (--rz-*), which every page loads, so
     there are no fallbacks. --nav-h is the header's resting height and is
     reserved as top padding — never measured (docs/responsive-breakpoints.md).
   - The accent is a class per market (.rmh--forex …), not an inline style, so
     js/market-header.js swaps one class when js/market-specs.js switches
     market without a page load.
   - The CTA is the site's .rz-btn.rz-btn--gold; the package's .rmh__btn is gone.
   - Breakpoints are on the ladder: 1180 → 1199.98, 900 → 991.98, 420 → 575.98.
   - text-align is `start`, and the artwork bleed and masks have .rtl mirrors,
     because the Arabic copy lays this out right-to-left.
   - Navy in both themes, like the homepage .rz-hero. The artwork colours assume
     navy; there is no light colourway.
