v0.3.1

Features

• Video export (MP4) — Export a lesson as a rendered video: a VideoTimeline IR with a pure compile pipeline #913, an L1 Hyperframes emitter with in-browser frame collection and ZIP export #931, and a service-backed MP4 render with in-app one-click export #937 (by @cosarah) — built on a shared orchestration spec in lib/choreography #890 (by @cosarah) and persisted TTS audio durations #862 (by @cosarah)
• Server-backed runtime storage — A pluggable storage seam for classroom runtime state: @openmaic/storage KV + asset primitives #858, a normalized DocumentStore #860, RuntimeStore sessions with append-only records #880, a DSL runtime envelope #870, device-anonymous learner identity #885, a runtime-event outbox with dual-write #893, cutovers for PBL learner state #902 #922 and chat sessions #926, and an HTTP backend contract with a Postgres backend and reference server #946
• Editor: direct manipulation — Select and drag slide elements #859, 8-point resize + rotate handles #881, marquee multi-select with multi-element drag #888, and a draggable insert toolbar #912, scaffolded as the @openmaic/renderer v2 editing surface behind a machine-enforced import boundary #853 #855
