Settings panel "coming soon" stubs replaced with live controls: - Draw Mode toggle (Draw 1 / Draw 3): new games read draw_mode from SettingsResource instead of the previous game's mode. Falls back to the current game's mode in headless/test contexts where SettingsPlugin is absent. - Theme selector (Green → Blue → Dark → Green): SettingsChangedEvent drives TablePlugin's background Sprite colour so the table re-colours immediately without a restart. - Music Volume [−]/[+]: dedicated kira sub-tracks created for SFX and music on startup. SFX sounds are routed to the SFX track; the music track exists for future ambient audio. Both volumes are set on SettingsChangedEvent and at startup. Also fixed: time_attack timer_expiry test double-fires when MinimalPlugins time delta is nonzero — removed the intermediate 0.001-remaining update step.
