Golden Balloon v0.3.2

A user-facing visual quality and correctness release.

Highlights:

• sharper runtime-derived SDF text in Remastered mode
• fixes the banana-collection sparkle streak
• fixes the subtle lower-screen road/sand fog flashing
• RDP-correct screen-linear shade and fog interpolation
• exact, bounded sprite layouts and measured moving-texture mipmaps

The browser build remains bring-your-own-ROM: ROM data stays local to the browser and is never uploaded. Published from source tag v0.3.2; source commit 415e2df85cbac1dd9afe412f1627dc8320e3b6d4.
