Studio per-vertical native demo capture (UX-14)

Summary

Per-vertical examples and a native-only studio-verticals-demo.mp4 — HTML vertical mocks archived; record-studio-verticals-demo.sh exits 1 without native frames.

Agent continuation

  1. Read — docs/demo/VERTICALS-RECORDING.md, packages/li-studio/examples/verticals/, deploy/studio-demo/archive/README.md.
  2. Run — lic check packages/li-studio/li-tests/smoke/studio_vertical_profile_roundtrip.li; LIG_HOST_PRESENT=1 ./scripts/record-studio-verticals-demo.sh.
  3. Next — Wire STUDIO_DEMO_PROFILE into studio_shell_demo_frame / li-studio-demo window capture; retire CPU framebuffer stub when wgpu present is stable.
  4. Blocked — Full domain packs (li-sim-automotive, export.print, adaptive drug GUI) remain PH-SIM / PH-GD follow-ups.

Not changed

  • studio_profile_* id table / runtime li_rt.c mapping
  • Full wgpu swapchain product capture from shipped li-studio-demo binary
  • li-langverse/studio org repo sync

Breaking

N/A — demo capture path stricter (no silent HTML fallback).

Security

N/A — local native capture; archived static HTML not used in user MP4.

Performance

N/A — no bench threshold changes.

Downstream

  • studio org repo: mirror examples/verticals when syncing from lic.
