Title: Side A — After the Last Train Exact creative prompt: Handcraft a warm analog listening-room experience called Side A. Draw a terracotta album sleeve and a large grooved vinyl record entirely in CSS. Use espresso brown, amber cream, italic serif lettering and intimate track-list typography. Present a fictional jazz quartet and three track moods. Play should actually synthesize a quiet three-note chord via Web Audio after user interaction, animate the disc and waveform, and pause correctly; track selection changes the chord. Clearly disclose synthesized audio and imaginary record. Keep the page responsive, offline, dependency-free and self-contained, with reduced-motion support. Description: An affectionate analog music object, combining the tactile graphic language of a record sleeve with a small, functioning browser-based ambient player. Major visual techniques: Repeating radial vinyl grooves; paper-like line texture; warm hard-edged sleeve; rotating disc; animated equalizer; serif/sans pairing. Intended interaction model: Play or pause a locally synthesized ambient chord and choose between three chord-based tracks.
