- Add canvas-drawn comet head, arrival fireball, and damage-radius ring textures in Fx.js, replacing the old single-dot streak/ring combo
- Switch all ram-related (and general glow) sprites from ADD to SCREEN blend to fix the "dark box" artifact over semi-transparent nebula backgrounds
- Introduce ember trail particles that linger ~1 s behind the hull during the dash, plus a flickering comet head that rides the ship and is released on impact
- Add `ramBlast()` impact sequence: ignition flash, blooming fireball, exact damage-radius ring, shock ripples, and debris sparks
- Wire in the heaviest camera shake beat (`ram`) and layer the data's sfxEvent under a thunder boom at impact
- Bump skill fx `ringLifeMs` to 480 so the damage-radius ring lingers long enough to read
- Add dev CDP harnesses (`cdp.mjs`, `ram-shot.mjs`, `ram-video.mjs`) and reference stills/video for the charge's three key frames
