    "1.2.0 — Reconciled variant naming to file content. logomark-white.svg + logomark-charcoal.svg are now true transparent marks (white-on-transparent / charcoal-on-transparent). Removed redundant *-transparent variants. Variant set reduced from 6 to 4: Charcoal, White, Bjarmi Card, Bjarmi on Offwhite. PNG + WebP regenerated.",
    "1.1.0 — Reconciled brand teal to system accent. Logo accent is now Bjarmi #87A6A6 (was #7F9390). SVG + PNG + WebP regenerated. AI source still references the old color and will be updated separately."
