TITLE: The Clockmaker's Orrery FILE: 004-brass-orrery.html === PROMPT (exact prompt used) === Create "The Clockmaker's Orrery", an interactive mechanical model of the solar system in the style of an 18th-century brass instrument. Parchment background (#efe3c6 with a subtle radial vignette and paper fibres from layered gradients), deep ink lines (#2b1d0e), and brass/gold metallic gradients (#b8860b → #f3d27a → #7a5410) for arms, rings and gears. Centre: a glowing sun; eight planets on brass arms orbiting at correct relative orbital periods (Mercury 0.241 y … Neptune 164.8 y) with log-compressed distances; an engraved zodiac ring with degree ticks around the edge; interlocking gears in a corner that rotate in sync with simulated time. Typography: engraved-looking serif small caps ("Iowan Old Style", "Palatino Linotype", Palatino, "P052", Georgia, serif) with generous letter-spacing. UI: a brass-styled readout of the simulated date, a speed dial (pause, 1 day/s, 1 month/s, 1 year/s), and click-a-planet to open an ornate cartouche with its name, period and a short engraved description. Delight: optional tiny ticking sound (Web Audio, after a gesture) and hover glints on the brass. SVG for the instrument, requestAnimationFrame for motion. SHARED REQUIREMENTS (apply to every page in this 100-page collection): 1. One standalone HTML5 file. All CSS inline in
