Fasalveer

Build "Fasalveer" (फसलवीर), a cinematic crop-protection brand site for Indian farmers. Next.js 16 + raw three.js + GSAP ScrollTrigger + Lenis + Tailwind v4. Green and filmic but simple to use on a mid-range Android phone, with an English / हिंदी toggle (every string in src/lib/content.ts as { en, hi }; DM Serif Display + Tiro Devanagari Hindi for display type, Mukta for body).

Hero: the Seasons Ring, a floating cut-away soil diorama (strata walls with roots and pebbles drawn on canvas) split into three 120° fields. The scroll is one continuous film over stage.progress:
- hero: dawn haze, young crops.
- Kharif: monsoon rain, paddy (instanced grass clumps and the rice model in reflective water) and procedural cotton. Caterpillars crawl, rot patches spread, then a drone sweeps the field spraying mist.
- Rabi: winter fog, wheat (one stalk from the wheat model, greenified in the shader) and procedural mustard. Aphids cluster and rust spreads, then a blue shield curtain sweeps across and ladybugs return.
- Zaid: summer sun, tomato, maize and sunflower rows on drip lines. Grasshoppers hop and weeds spread, then a green shield clears them.
- harvest: golden hour from above, grain ripens, bees and butterflies fly, a tractor laps the rim.
- products: a soil podium rises from the ring's centre with six procedural 1 L bottles (lathe body, ribbed cap, canvas wrap label with the bilingual name and toxicity diamond), turned by scroll or click.

One crop shader (scene/plants.ts) drives every field with uniforms: grow, sick (noise patches + droop), heal front (a sector-local angle swept by the drone or shield), ripe and wind. During each season's protect phase the ring turns with the sweep, so the action stays in frame.

Below the world (opaque, so rendering pauses): a three-tap crop finder (crop → problem → product, dose, timing, WhatsApp), the drone film opening to full bleed with "Right product. Right dose. Right time.", a horizontal safe-spraying track with the Indian label-triangle legend, farmer stories with a portrait video, lab-to-village band, dealer finder and call-back form, and a footer over the night ring with fireflies.
