Weapons: a courtside rack you pick from + pixel-art HUD

Tins now accumulate on a courtside rack (cap 3) instead of replacing each other; a PLAIN slot banks specials for later, and GUN is a charge you pop for an auto-fire burst. Tap the rack or press 1-5 to choose what your serve throws. A fresh delivery auto-equips but never overrides a deliberate PLAIN, and the 1:1 sudden-death duel forces plain balls.

HUD gets real art: generated pixel-art weapon icons, an ornate Wimbledon scoreboard PNG backing the live text (no more code-drawn boxes on top), and a bundled Silkscreen pixel font replacing the system serif. Rack tiles get padding, count-over-label alignment, and an infinity marker on the ball.
