Windows installer no longer auto-downloads models; points to the Models tab. synapse/hardware.py detects RAM + best-effort VRAM and a curated catalog; GET /models/recommended annotates each model with fit (gpu/ram/no); the Models page shows detected RAM/VRAM with fit badges and per-row Pull buttons.
