    REVLO PLATFORM
    PART 5 — PILLAR BRAND COLORS
    ---------------------------------------------------------
    Only 4 of the 6 platform cards get a pillar identity.
    Finance and Intelligence intentionally receive NO modifier
    class here — they fall through to the generic --primary
    defaults set on .platform-card in Part 1, so nothing above
    needs to change for them, and removing them later is a
    clean PHP-only deletion with zero CSS cleanup required.

    Requires one small addition in index.php: add the matching
    modifier class to each of these 4 <article class="platform-card">
    tags (see the accompanying note for exact before/after).

    Garage note: unlike the other three pillars, its "identity"
    swatch (#E8AF12) is too light for AA text contrast on white,
    so --card-ink deliberately uses its darker variant
    (#B8850A) instead of the raw identity gold — the bright gold
    is still used for the glow/wash/line, just not for text or
    icon glyph color. This mirrors the distinction your own
    Garage token file already draws between --brand and
    --brand-dark.
