TITLE: Silicon — Living Circuit Board FILE: 073-circuit-board.html === PROMPT (exact prompt used) === Build "Silicon — Living Circuit Board". An SVG printed circuit board in rich green solder mask (#0a4d2e with subtle texture) with gold traces and pads (#d4a537 with highlights), white silkscreen labels (component references such as U1, R12, C4, "REV 2.1"), chips (black epoxy with pin legs and printed markings), capacitors, resistors with colour bands, LEDs and a crystal oscillator. Signals — glowing pulses of cyan (#3cf2ff) and warm white light — travel along traces from chip to chip, routed along a graph of trace segments. Interaction: hovering a component highlights all of its connected traces and shows a spec tooltip; a "power" switch boots the board (LEDs light in sequence, a small OLED component shows boot text); clicking a chip "overclocks" it (faster pulses, a slight heat shimmer); a "logic probe" cursor mode shows voltage readings on traces. A title block in silkscreen monospace in the corner. Scales responsively via viewBox. SHARED REQUIREMENTS (apply to every page in this 100-page collection): 1. One standalone HTML5 file.
