<h1>Timer panel — three redesigns</h1>
<p>Three ways to shape the timer dropdown, all in the shipped instrument-console faceplate language
(same tokens, lamps, console keys, engraved labels, and tabular readouts as the net / bt / sound panels).
Each is a <b>working prototype over one shared engine</b> that mirrors wtimer + the PanelModel: add / cancel / pause /
resume, promote to the bar slot, per-type presets (add and delete chips), freeform entry with the same validation,
stopwatch lap + stop-and-save, the soonest-fire queue sort, the 10-item cap, and a real completion + notify on fire.
Try each: add a timer, watch one count down and fire, promote a row, pause a stopwatch, delete a preset chip.</p>
</header>
<h2><span class="tag">A</span> Rack unit — the faithful list</h2>
<p class="blurb">The closest sibling to the net / audio panels: a vertical stack you scan top-down. Header with the live
count and <b>CLEAR ALL</b>; one output-well row per item, soonest-firing on top; each row carries a lamp, glyph, label,
the big countdown, and inline pause / promote / cancel keys. Create strip lives at the bottom — pick a type, tap a preset
or type a duration, name it, ADD. Safest port of what already shipped.</p>
<div class="desk"><div class="panel" id="panelA"></div></div>
<h2><span class="tag">B</span> Transport deck — one hero, a track list</h2>
<p class="blurb">A cassette-transport shape. The <b>primary</b> item (the one in the bar glyph slot) gets a hero readout with a
progress ring and chunky transport keys; everything else is a compact track list underneath. Click a track to promote it into
the hero seat; the ‹ › keys cycle the primary. Puts the timer you care about front-and-centre, the rest one glance away.</p>
<div class="desk"><div class="panel" id="panelB"></div></div>
<h2><span class="tag">C</span> Channel-strip board — a mixing desk of timers</h2>
<p class="blurb">The mixing-console metaphor: every item is a vertical channel strip on a board, its fader draining from the top
as time runs out (a stopwatch fills instead, tinted slate). Read all your timers at once like meters on a desk. Click a strip
header to promote it; the trailing <b>＋ NEW</b> strip is the create surface. The most spatial, most stereo of the three.</p>
