Landing page: explorer.html widget mockup
A visual mockup of the Pimoroni Explorer Kit (PIM744) - yellow PCB body, 6 coloured buttons (A/B/C left, X/Y/Z right) flanking the central 320x240 LCD, piezo + mini-breadboard at the bottom, USB-C / RP2350 silkscreen. Canvas mirrors the firmware UI: VARASYS logo + version + run-state dot in the header (3-channel lerp for the per-beat pulse, no more red-channel-only blend bug); setlist tab + track name + big BPM + bar/time meters; pad grid up to 6 lanes with main-beat squares + subdivision circles + vertical gridlines. Inputs: A = play/stop, B = tap, C = next setlist; X/Z = prev/next track with 350 ms first-repeat + 120 ms repeat; Y = -1 bpm (after 1.5 s held step = -5); X+Z chord within 100 ms = +1 bpm (mirrors Y). Keyboard: A B C X Y Z + space. Landing page (index.html) Explorer pane now points at /explorer.html with h:500 (the LCD is half-height of the Kit's so the widget is more compact). The /info-explorer.html embed handler still works for the "Specs & info" link. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
