/* ==========================================================================
   Shared design contract with the rest of the site.
   --------------------------------------------------------------------------
   Sunray and Gridnorth are the same product and should read as it. What is
   shared, and what deliberately is not:

   SHARED   typeface (IBM Plex Sans / Mono), 2px radius, 48px minimum tap
            target, monospace for anything read aloud or transcribed.

   DIVERGES background and accent. The site sits on #10191D with a #B8650F
            accent; Sunray sits on pure #000000 so unlit AMOLED pixels emit
            nothing, and takes a brighter #FF7A1A because the site accent
            measures 4.91:1 on black where the brighter one measures 8.05:1.
            The red-light theme has no counterpart on the site at all. These
            are operational requirements — light discipline and night
            legibility — not stylistic drift, and scripts/test-contrast.mjs
            holds both themes to the measured floors.

/* Red light: monochromatic, preserves scotopic adaptation and NVG use.
 *
 * Pure red on black tops out at 5.25:1, so the entire usable band for AA body
 * text is #EB0000 to #FF0000. Dimming by luminance is therefore not available
 * here: an earlier build used #A10000 for every field label, which measures
 * 2.52:1 and is unreadable in the one mode meant for darkness. Hierarchy in
 * this theme comes from weight and letter-spacing instead, and the colours
 * below are the measured floors:
 *
 *   --fg      #FF0000  body text
 *   --fg-dim  #ED0000  secondary text, still AA
 *   --line-hi #B90000  interactive borders (WCAG 1.4.11 non-text)
 *   --line    #6B0000  decorative rules only, never a control boundary
 *
 * Every figure is measured against --panel as well as the page background,
 * since the panel is marginally lighter and lowers the ratio. --line is the
 * one token exempt from 1.4.11: it draws grouping rules and card edges, never
 * the boundary of a control. scripts/test-contrast.mjs enforces the rest.
