Logos: the brand is now a consistent lockup — wordmark image + a crisp CSS "Simplifying Complexity" tagline — in the shared header, device silkscreens (teacher/stage/micro), the player (was a CSS text box) and the showcase canvas (was drawn text; now the real logo image + tagline). Cropped the baked tagline out of logo-light.b64 so both themes render the tagline once. Renamed device silk logos to .dev-logo so they no longer shrink the shared header logo. Embeds: every form factor now loads its default set lists when embedded with no config — and the Concepts landing embeds them that way (viewport loads <device>?embed=1 with no forced #p=; the program box reflects what the device reports and only overrides on explicit Load).

PM-S "Showcase" — a display-piece metronome shaped like a classic pyramid wind-up
|
||
unit. The pendulum is the whole show: a single RGB LED bar where every lane's
|
||
subdivisions / accents are combined ALONG its length (each lane is a moving point
|
||
of light), it carries a printed TEMPO scale on the vertical axis, and a sliding
|
||
WEIGHT sets the tempo (drag it — up = slower, like the real thing). The canvas is
|
||
transparent outside the body. There's no on-screen power switch: the real unit
|
||
starts when you lift it from its holder / set it swinging — here that's an external
|
||
button. Latency-compensated visuals. Shares src/engine.js.

|
||
<p>A metronome as an object: the silhouette of a classic pyramid wind‑up unit, but the swinging pendulum is
|
||
pure <b>RGB light</b>. The whole bar is the display — every lane's subdivisions & accents ride along its
|
||
length as moving points of light (all meters combined), a printed tempo scale runs up the vertical axis,
|
||
and a sliding <b>weight</b> sets the tempo just like the mechanical original.</p>
|
||
<p>It's a beautiful, glanceable tempo reference for the shelf, the studio, or a shop window: accents glow
|
||
amber, normal steps cyan, ghosts soft violet, and the pendulum eases to each beat exactly as a weighted rod
|
||
would. It runs the same grooves as everything else (load any program string), plays the click through a
|
||
small speaker, and is powered over USB‑C with a second "thru" port to daisy‑chain. There's no power switch —
|
||
the real unit starts when you lift it from its holder / set it swinging. No instrument I/O; it's a showpiece.</p>
