TITLE: THE DARKROOM — a film development timer
PROMPT: Create 'THE DARKROOM', a film-development timer: the whole page is a dim amber safelight room — deep red-amber palette, vignette edges, an enamel developing tray with three liquid baths (develop, stop, fix) rendered as gently animated liquids, and a circular timer with a rotating red hand. Interactions: an AGITATE button rocks the tray with liquid slosh as a paper sheet flips between baths at each stage; the timer runs each stage with ticking audio (WebAudio, gesture-gated, mute toggle) and quiet stage cards (DEVELOP 8:00 / STOP 0:30 / FIX 4:00 / WASH); as development completes, a hidden gradient 'photograph' slowly fades IN as if emerging in the developer bath. Nostalgic, tense, deeply atmospheric.
DESCRIPTION: A working darkroom timer under safelight: red-amber room glow, film-vignette edges, and Courier instrumentation. A circular canvas timer with sixty ticks, glowing progress arc, and red sweep hand counts down each stage; clicking any of the four quiet stage cards (DEVELOP 8:00 / STOP 0:30 / FIX 4:00 / WASH 5:00) jumps to that bath, its tray label lighting below. The enamel tray holds an animated sloshing liquid; clicking it agitates — the tray rocks with damped rotation and a liquid tick. Inside the bath, a framed latent photograph (a pier at dusk drawn in grays with sun, posts, birds, and emerging grain) fades IN as DEVELOP progresses and reaches full strength after FIX; START/PAUSE (per-second ticks in the final ten seconds), stage-complete chimes, and a sound toggle defaulting off.
TECHNIQUES: canvas dial with generated tick ring, progress arc, and sweep hand; staged countdown state machine across four chemistry baths; grayscale latent photograph painted with reveal-scaled gradients and grain density; damped agitation rocking; WebAudio square ticks and sine chimes behind a default-off gesture-gated toggle; CSS sloshing liquid keyframes; safelight radial ambience and vignette.
INTERACTION: START/PAUSE the run; click stage cards to jump baths; click the tray to agitate (it rocks); keep sound off or enable ticks and chimes; watch the photograph emerge in the developer and fix to permanence.
