BenStullsBets ea530b3df6 fix(sim): double-buffer video so morph->loop handoff doesn't stall

Operator eyeball: a jolt/pause when the morph ends and the next altitude's loop
loads. Root cause: swapping vid.src to the base + seeking to the tail reloaded the
ON-SCREEN element (decode + seek stall). Now a dedicated #vid-loop element carries
the steady-state base loop; during a scrub it is PRELOADED to the clip we're heading
toward, seeked to the tail and paused on that exact frame. The paint shader reads the
active source (busy ? morph : loop), so landing is an instant source swap — no reload,
no seek. E2E asserts the loop element is armed + playing from ~3s after landing.

Simulator E2E (Playwright)

Browser end-to-end tests for the Human Experience Filter simulator. The §9 pipeline requires an E2E browser tier for any UI surface; this is that tier.

What it covers

tests/altitude-lock.spec.ts drives the real simulator and asserts the altitude-morph behavior:

Zooming to a new altitude plays the morph that matches the clip it lands on (forward zoom-in, and .rev zoom-out).
After landing, the clip is locked — it does not change while parked (no secondary swap, no re-roll).

The played morph paths are read from window.__hefMorphs (a diagnostic array populated by advance() in static/app.js), which is reliable even when a morph is served from the in-memory blob cache. The locked clip is read from the Dev-Mode #scale-name readout.

Running

Prerequisites: the project Python venv on PATH (the Playwright webServer boots uvicorn simulator.app:app from the repo root), Node, and the Chromium browser.

# from this directory (simulator/e2e)
npm install
npx playwright install chromium
npm test

playwright.config.ts starts uvicorn on port 8099 automatically (reuseExistingServer locally) and points the tests at it.
