Build targets for every shipping variant: make test → self-tests (currently 4 green) make native → libac_rast.a for linking into ac-native make wasm → four modules (baseline / simd / threads / full) README captures the integration plan, the cross-browser compat table (what features unlock on which Safari/Firefox/Chrome versions), and the COOP/COEP prereq for the threads+SAB parallel path. Status checklist marks what's done and what's next so the next session doesn't need to re-derive the plan from the commit log.
