Undiscovered (never-seen) terrain was leaking through fog on both the
main map and minimap; only the lit(visible) vs unlit(seen) distinction
worked. Root cause: unexplored overlay was sub-opaque + undersized.
- fog_renderer.gd: UNEXPLORED_COLOR alpha 0.85 -> 1.0 (opaque); edge-fade
softening now gated to the FOGGED state only — unexplored tiles stay
fully opaque even at vertices bordering a visible tile (was revealing
undiscovered terrain along the exploration frontier).
- design-tokens.json -> regenerated ui_theme.tres: fog.unexplored
alpha 0.90 -> 1.0 (fixed at token source, not hand-edited).
- minimap.gd: unexplored now drawn as a full tile-pitch opaque cover
instead of a 3x3px dot (the dot left ~5px gaps at minimap scale,
leaking terrain). fog.explored (seen dimming) left unchanged.
Verified on apricot via iter_7q_worldmap_visual_proof with fog ENABLED:
undiscovered renders solid black on map + minimap, clean hard frontier,
lit tiles unaffected. (GUT cannot prove this — render-verified.)
