TITLE: THE LAST LIGHT — beacon station
PROMPT: Create 'THE LAST LIGHT — beacon station', a lighthouse night-watch page: a rocky point under stars, a lighthouse whose beam (animated cone) sweeps the sea in real seconds; passing ships respond — a dot brightens when the beam crosses them and a ship's horn occasionally answers (WebAudio, gesture-gated, rare); fog rolls in bands; the keeper's log self-writes wry entries; a Fresnel lens close-up sparkles as it rotates. Interactions: dragging the beam changes its sweep speed and phase; a FOG slider thickens haze and reddens the beam; the keeper's log accepts your own entry; ships clickable for a silhouette card; dawn mode slowly grades the whole scene to pastel morning and turns the light off. Lonely, atmospheric, gentle drama.
DESCRIPTION: A night watch at beacon station 9: a striped tapered lighthouse on dark rocks under fading stars, its lantern room glowing and sweeping twin gradient beam-cones across the sea. Ships cross at various distances; when the beam catches one it lights up, sometimes answering with a low sawtooth horn, and opens a silhouette ID card (MV Kestrel, Alba Fjord…). Fog bands drift in layers that redden and swell the beam; dragging near the tower redirects the beam and changes its sweep speed; the keeper's log self-writes wry entries every so often and accepts your own; LET DAWN COME runs a slow full-scene regrade to pastel morning — the lamp dies, the sky warms — before night falls again.
TECHNIQUES: rotating dual light-cone gradients with angle math, ship agents with beam-intersection detection (angular distance), ship lighting + horn response, layered fog band gradients, dawn interpolation across sky/sea/tower palettes, keeper's log feed with user entries, radial-gradient lamp glow and sea shimmer, drag-to-steer beam with speed persistence.
INTERACTION: Drag near the lighthouse to steer the beam and set its speed; fog slider thickens the haze; click lit ships for their silhouette card; write your own log entry; let dawn come and watch the station sleep.
