New section: Community Units (3D)

The community-made units have moved out of the Unit Database into their own gallery: Community Units 3D.

• 223 community units from the classic community unit archive (Units.ufo), each rendered from its own 3DO model — 25 of them already animated 1:1 from their own COB scripts (validated loops, seam-checked); the rest show their static model render until their animation is done.
• Each unit dialog carries the stats, the COB timeline, the in-game build pic and the packaged .ufo download with SHA-256 and file list.
• The Unit Database now lists only the original Cavedog data (276 units) again — the community cards used to be mixed into the same grid.
