/* ============================================================
   footer-sig.css — LUMIN attribution (additive, footer-scoped)
   ------------------------------------------------------------
   Loaded AFTER style.css. Defines its own class namespace only
   (.footer__sig*) — it overrides nothing in the frozen base by
   cascade and touches no other footer content.

   Reproduces the approved treatment exactly:
   subordinate to GRACIELLA, monochrome reverse on the dark
   footer, matched opacity, fixed 16px height, vertically
   aligned with the © line. No hover, no glow, no badge, no link.
