<title>09 framework input invariants</title>

<p>Goal: type <code>abc</code>. Page asserts React-style invariants: <code>beforeinput</code>
fires <em>before</em> <code>input</code>, both per-character, <code>inputType==="insertText"</code>,
value mutates between events, and no <code>compositionstart</code> for plain typing.</p>
<input id="t" placeholder="type abc" style="font-size:18px;padding:8px 12px;width:240px">
