  "description": "GitHub's Primer dark theme reading — accent-emphasis #1f6feb on canvas-default #0d1117 (Bunker Base) with the documented Primer surface ladder #161b22 → #21262d. Foreground default #f0f6fc, muted tier #8b949e + subtle #6e7681. The \"code-host workspace dark\" register: clean cobalt-blue accent on a near-black-blue canvas, matching primer.style/foundations primitives verbatim.",

    "Don't substitute accent-emphasis with another blue — Primer #1f6feb is the documented hex; deviation breaks the design-system fidelity.",

    "Don't substitute the surface ladder — #0d1117 → #161b22 → #21262d is verbatim Primer; collapsing tiers loses the elevation system."
