 * HUD-CORE-12 (#2803) — HUD readability enhancements.
 * Drop shadows and text treatments ensuring all HUD chip text is legible
 * over any busy canvas background (combat floaters, particles, dense enemies).
 * Applied via cascade from #hud-root; does not override chip backgrounds set
 * by individual chip modules.
 * Structural only — visual tokens deferred to Sprint 3B.
