Spent this session on polish and cleanup. Reworked the UI and CSS myself — set up a color palette with variables so the whole game re-themes from one place, and simplified a lot of the styling.
Also fixed a performance bug: the game ran fine in Safari but lagged in Chrome. Turned out canvas shadow-blur is way slower in Chromium, so I cut it off the small stuff (dust, particles) and leaned on the additive glow instead. Runs smooth now.
Still fixing the plinko bonus round and cleaning things up. More soon.
