TITLE: GLASSHOUSE — the hot shop
PROMPT: Build 'GLASSHOUSE', a glassblowing studio toy: a dark hot shop with a glowing furnace mouth; a blowpipe with a molten gather whose glow shifts white→amber→cherry as temperature drops; you shape the piece — HOLD to inflate (the gather swells with wobble physics), drag sideways to stretch, the marver table flattens, and turning the pipe keeps symmetry. Palette: near-black shop, incandescent glass oranges, cool finished-teal. Interactions: BLOW (hold), TURN (drag rotary), tools (jacks pinch a neck, block rounds it); a heat meter forces reheats in the glory hole or the piece cracks with a sad tink; finishing anneals the piece into a glossy teal vessel for your gallery shelf; shelf stores your best five. Physical, incandescent, craft-true.
DESCRIPTION: A dark hot-shop diorama: a brick furnace with a glowing animated mouth (click to gather molten glass), a glory hole for reheats, and a full-viewport canvas where your blowpipe follows the pointer. The gather is a radial-gradient blob whose color honestly tracks its heat — white-hot → amber → cherry → cold teal — with shadow-blur glow, breath wobble when inflating, gravity stretch when hot, and spark particles rising. Tools: hold to blow (swells only while hot), turn (spin symmetry), jacks (pinch a neck), block (round it flat); a heat meter drains constantly, forcing trips to the glory hole; work a cold piece too long and it cracks (filtered-noise tink, three strikes and it's gone). Anneal at the right size and temperature to sign a glossy teal vessel onto the gallery shelf.
TECHNIQUES: heat-state color mapping with radial-gradient and shadowBlur incandescence, hold-to-inflate physics with wobble and gravity stretch, pointer-following blowpipe with quadratic curve rendering, tool state machine, WebAudio sine puffs and highpass-filtered noise crack, spark particle field, anneal gating by size/temperature, shelf state.
INTERACTION: Click the furnace to gather; hold BLOW (or hold on canvas with blow tool) to inflate while hot; TURN spins the pipe; jacks/block tools shape; click the glory hole to reheat; watch the heat meter and anneal at 26+ size below 45% heat to shelf the piece; cracks punish neglect.
