/* ============================================================
   Ax0s — Molten Ledger, demoted.
   Coal is the page. Cream is the voice. Amber survives as rules,
   labels, data-ink and CTAs — plus exactly ONE drenched plate per
   page, so the brand surface reads as punctuation, not wallpaper.
   Hot orange is reserved for change: strikes, deltas, live marks.
   Depth is tonal and drawn — no shadows, no radius, no glass.
