## Shared "engraved bronze plaque" look for every box in the game — aged gold on
## dark leather, a chiselled heavier bottom edge and a warm drop shadow, so the HUD
## and the menus read as the same arena furniture instead of a stack of generic
## rounded panels. Pair with UiFonts (Cinzel) for the full Colosseum feel.

## The signature plaque: leather fill, gold-bronze trim with a heavier chiselled
## bottom edge (weight sinks to the base like an engraved tablet), crisp corners and
## a soft drop shadow. `accent` recolours the trim — pass a per-ability colour for
## HUD tiles or CREAM for a hot/hover state; a transparent accent draws a frameless
## plate (still shadowed).
