Replace the shiny brushed-aluminium look with a bead-blasted matte-black anodised finish on both the stage and micro mockups: - flat dark graphite case + a fine bead-blast micro-texture, and the specular top highlight removed, so the case doesn't reflect stage lights; - light laser-etched legend colour (--silk) and the light VARASYS logo variant on the dark case; lighter metallic rims on the top-edge connector openings so they read on black; - stage BOM enclosure + comments updated to "die-cast aluminium, bead-blasted, matte-black Type II anodise, laser-etched legends".

<!--
|
||
"As-built" variant of the PM-1 player: the same firmware/engine, drawn with the
|
||
parts you'd actually solder for an RP2040 build —
|
||
• a 2.0″ 320×240 colour IPS TFT (ST7789, e.g. Pimoroni Pico Display 2.0):
|
||
the upgrade from the cramped 128×64 mono OLED — full colour, smooth type,
|
||
hi-DPI. It also draws all lane patterns (each lane's steps — accent /
|
||
normal / ghost / mute — with the playhead), so there's no separate LED bar;
|
||
• controls: a big PLAY up top (a plain arcade button — it does NOT change
|
||
while playing; the screen shows transport state; an illuminated/RGB arcade
|
||
button could reflect it), then a row of PREV (far left), a recessed
|
||
thumb-roller for tempo + TAP (centre), and NEXT (far right);
|
||
• top-edge I/O (all jacks on the top edge — cables run up off a pedalboard;
|
||
the top view shows the ~45 mm total thickness): external trigger in
|
||
(footswitch), a 1/4" instrument pass-through
|
||
with the click mixed in the ANALOG domain (DAC → summing op-amp → balanced
|
||
line driver), a shared 1/4" balanced-TRS main out, plus an analog monitor
|
||
amp + speaker. Powered from a standard 9 V DC pedal jack (2.1 mm centre-
|
||
negative, pedalboard-friendly) or USB-C (also carries config), in a
|
||
bead-blasted matte-black anodised aluminium enclosure (no glare on stage).
|
||
Beside the device: a top-edge view and a bill of materials. The front and top
|
||
views carry inch dimensions (≈ 4.7 × 5.5 × 1.8 in / 120 × 140 × 45 mm).
|
||
Compare with the initial /player.html. One file, no deps; shares src/engine.js.
