   OMEIDA TRADING 105 — Design tokens

   Deep navy sections with the logo green as a bright accent. The green does the
   job a contractor site's yellow does, but it is OMEIDA's own brand colour.

   Contrast audit (WCAG 2.1, verified with a script — see docs):
     #FFFFFF on #0B2E42 .... 13.15:1  AAA   body copy on navy
     #8AC24B on #0B2E42 ....  6.67:1  AA    green accent text on navy
     #1B2E08 on #8AC24B ....  9.40:1  AAA   text ON a green button
     #4E6B24 on #FFFFFF ....  5.90:1  AA    green that may carry text on white
     #8AC24B on #FFFFFF ....  2.12:1  FAIL  GRAPHIC USE ONLY on light
     #111A20 on #FFFFFF .... 17.9:1   AAA   headings
     #3E4A52 on #FFFFFF ....  9.24:1  AAA   body copy
     #6B767D on #FFFFFF ....  4.79:1  AA    muted copy

   RULE: --green is a fill, never text on a light background. Green text on white
   uses --olive. Text sitting ON green uses --green-ink.

    /* ── Type ──────────────────────────────────────────────────────────────
       Two faces, assigned by ROLE — not by taste, so the site stays consistent:

       --head (Montserrat)
         headings (h1-h4) · eyebrows · buttons · primary navigation, including
         the dropdown and mobile menu · uppercase letter-spaced micro-labels
         (stat labels, contact keys, form labels, footer titles, categories) ·
         numerals and stat figures

       --sans (Source Sans 3)
         body copy · list items · descriptions and supporting sentences ·
         form inputs and their values · addresses · secondary links
         (footer navigation, breadcrumbs, the utility contact strip)

       When adding a component, decide which of the two roles its text plays
       and set the family explicitly. Text that inherits by accident is how
       the two faces drift apart.
