Tier 3g: name the three render rules that were copied instead

Tier 1, step 4b: stop one bad entity killing the view (A7, A8)

Add Observer Mode: a free-look spectator over the Odyssey galaxy

P8 Combat Depth: veterancy chevrons + tiered destruction visuals and audio

Give the Leviathan a real capital-ship hull

Remove Miner, Engineer, and Technician — Worker builds everything again

Give Miner, Engineer, and Technician their own unit sprites

Add the Helium Bomb: a mobile, arm-then-detonate doomsday unit

Fix rendering waste: redundant Set allocs, stale DPR icon cache, swallowed errors

Fix the scout-a-building crash: unexported drawEnemyPip + harden loop.js

Split render.js god file into cohesive render modules
