Me Here cb54b4d689 Preserve notation + grammar feature work (verified complete + green)
The parallel agent's full session, committed now that it's solo:
- Grammar: flam/drag/roll ornaments (f/F d/D z/Z, per-lane orns channel) across
  src/engine.js, pico-cp/pico-explorer/pico-scroll app.py, pico/main.py, rust/track-format,
  + golden vectors / conformance (tests/, rust/track-format/tests).
- Live-sync deep-sync: SysEx 0x44 SLSYNC + 0x45 LOGSYNC (docs/livesync-protocol.md, src/livesync.js).
- PM_E-2 notation: web engine (pm_e-2.html, build/deploy/index/embed wiring) + Rust device port
  (pm-ui draw_notation rewrite + LaneView.groups, pm-kit ViewMode, uisim notesim).

Verified: node tests/run.mjs 47 pass / 1 known; ./rust/run.sh green; pm-kit firmware + uisim compile.

<h1>Embed a PolyMeter widget</h1>
<p class="lead">Every PolyMeter form factor doubles as an embeddable widget. Drop one into any page with
a placeholder + one script tag — no build step, no dependencies. It loads in an iframe and is preloaded
with whatever <b>program / settings string</b> you give it.</p>
<p class="pick"><label for="ffSel">Show snippets for:</label>
<select id="ffSel">
<option value="editor">PM_E1 Editor</option>
<option value="pme2">PM_E2 Editor (Notation)</option>
<option value="teacher">PM_T1 Teacher</option>
<option value="stage">PM_S1 Stage</option>
<option value="micro" selected>PM_P1 Practice</option>
<option value="showcase">PM_D1 Display</option>
<option value="initial">PM_C1 Concept</option>
</select>
<span class="ff-name"></span></p>
<h2>Drop-in (recommended)</h2>
<pre id="snipDrop"></pre>
<p>The script replaces the <code>&lt;div&gt;</code> with an auto-sizing iframe. Here's the <span class="ff-name"></span>, live on this page:</p>
<div class="demo"><iframe id="demoFrame" title="live embed preview" allow="autoplay" style="border:0;display:block;width:100%;height:300px"></iframe></div>
<h2>Or a plain iframe</h2>
<pre id="snipIframe"></pre>
<h2>Form factors — <code>data-varasys-metronome</code></h2>

<tr><td class="k">data-setlist</td><td>A base64url setlist code (a whole set list) — share it from the editor.</td></tr>
<tr><td class="k">data-width / data-height</td><td>iframe size (default <code>100% × 300</code>; height autogrows to the widget).</td></tr>
</tbody>
</table>
<p>Under the hood the loader builds <code>&lt;page&gt;?embed=1#p=&lt;patch&gt;</code>; the page's <code>?embed=1</code> mode strips the
site chrome so only the widget shows. That's the same way our own Concept &amp; Info pages embed it.</p>
