TITLE: TERRA INCOGNITA — interactive fantasy atlas
PROMPT: Build 'TERRA INCOGNITA', an interactive fantasy atlas: a hand-drawn-feel map canvas (parchment base with noise, ink coastlines generated from a seeded blob algorithm, mountain hachures, tiny forest glyphs) of a procedurally named archipelago (Vor Sallow Isles, The Amber Reach …); a compass rose that spins lazily; sea monster embellishments in corners. Interactions: pan and zoom the map smoothly (transform-based, wheel and pinch-friendly); clicking regions opens a bestiary/gazetteer card with lore and a wax-seal stamp; REGENERATE re-rolls an entirely new archipelago with a fresh seed; a measure tool clicks two points for a leagues-scaled line with a flowing dashed animation. Explorer's delight, ink-and-paper soul.
DESCRIPTION: The cartographer's table: a 1600×1100 parchment map floats in lamplight on a dark oak desk (wood-grain backdrop, heavy drop shadow, brass frame). The map itself is drawn procedurally from a seeded LCG — 4–6 blob-coastline islands with double-inked coasts, radial sea tints, hachure mountain peaks, forest glyphs, two sea serpents, rhumb-line network, double-rule border, and a title cartouche carrying the seed number. Procedurally named regions (Vorholm Kingdom, Kestdor Free Isles, The Amber Reach…) get flag/anchor markers that open wax-sealed gazetteer cards with lore, exports, beasts, and population. Pan by dragging, zoom by wheel/pinch/buttons, regenerate rolls a whole new archipelago, and the measure tool draws an animated dashed line scaled in leagues.
TECHNIQUES: seeded LCG procedural generation (radial-polygon islands, syllable-table name synthesis), multi-pass canvas cartography (parchment fibers, rhumb lines, hachures, sea-serpent embellishments, cartouche), CSS custom-property transform pan/zoom with pointer + wheel + touch pinch, SVG compass rose, wax-seal gazetteer cards, animated stroke-dashoffset measure lines, wood-grain desk canvas backdrop.
INTERACTION: Drag to pan, scroll/pinch/buttons to zoom (0.4×–3×); click any flag or anchor marker for its lore card; REGENERATE re-rolls the entire world with a new seed; the measure tool drops two points and reports the distance in leagues with a flowing dashed line; the compass rotates lazily forever.
