 ## Milestone 5: Presentation
 
-- Portrait and art pipeline. Officer definitions can provide default portrait paths, classes can provide board `sprite` paths, items can provide transparent `icon` cutout paths, scenarios can provide map `background` paths, and the first generated officer portraits, unit sprites, item icons, and battlefield background are in `art/`.
+- Portrait and art pipeline. Officer definitions can provide default portrait paths, classes can provide board `sprite` paths, items can provide transparent `icon` cutout paths, scenarios can provide map `background` paths, and generated officer portraits, unit sprites, item icons, plus scenario battlefield backgrounds are in `art/`.
 - Unit sprites and animations. Board movement now has a short slide animation, attacks request class-specific motion profiles for infantry, archers, cavalry, command units, and heavy warrior/bandit units, and board units show class sprite tokens, team rings, class badges, low-HP warning rings, and small status pips for active support, debuff, poison, seal, snare, and disarm effects, with HUD summaries showing remaining phases.
 - Battlefield presentation. Maps can draw a high-resolution background under translucent terrain overlays, with terrain-specific detail patterns, connected road segments, shoreline/castle/forest/hill edge blends, and generic-enemy token marks.
 - Battle HUD presentation. Selected and hovered units now summarize battlefield role, movement type, current terrain move cost, defense/avoid bonuses, core stats, status effects, and gear so class identity reads alongside the visual tokens.
