Browse the full H3 grid across five zoom levels — from 86 km² ERA5 weather cells down to 0.1 km² field-level cells. Click any cell to open the detail sidebar with two tabs:

• Latest — terrain (elevation, slope, aspect), weather snapshot, vegetation indices, and soil properties. Each row is also a radio button that recolors the map by that feature.
• Historic — multi-year timeseries charts: NDVI history, temperature & precipitation, temperature range (mean vs min), solar radiation, and actual evapotranspiration.

The map recolors on every pan and zoom, fetching only cells in the current viewport via a ?bbox= API. Panel width is drag-resizable and persists in localStorage.

Pre-computed suitability scores (0–1) for 8 crops per res-9 cell, using a trapezoidal fuzzy membership function against monthly ERA5 climate data and SoilGrids soil properties. Scores are computed by the ETL pipeline and stored in the database; the app is read-only.

• Tab 1 — Crop Scores: 8 crop rows with radio buttons, CSS progress bars, and numeric scores (0.00–1.00). Selecting a crop radio recolors the map immediately.
• Tab 2 — Monthly Detail: Chart.js band chart overlaying the actual monthly climate value for this cell against the crop's ideal min/max requirement band — one feature at a time. Growing-season months only; off-season months show no band.

Color ramp: 0.0 = red (poor) → 0.5 = yellow → 1.0 = green (ideal)

Scored crops: Wheat · Barley · Sugar Beet · Sunflower · Maize · Chickpea · Lentil · Cotton

Pre-computed economic projections per cell per crop, built from suitability scores, FAOSTAT commodity prices, and TAGEM production costs.

• Yield estimate: ref_yield × (0.2 + 0.8 × score) — the 20% floor prevents unrealistic zero-yield cells.
• Net profit: yield × price − total_cost, where costs are TAGEM 2022 figures CPI-adjusted to 2024 (factor 1.40).
• Confidence bands: High ±20% (Wheat, Barley) · Medium ±40% (most crops) · Low ±60% (Cotton).
• ⓘ notes for Sugar Beet, Chickpea, Sunflower, Maize flag irrigation requirements, rotation constraints, and regional processing capacity limits.

Map color ramp: loss → break-even → profit (breakpoints at −500 / 0 / +500 USD/ha)

Draw a polygon over any area on the map and apply environmental override deltas — then watch cells re-scored in the background by a Celery worker.

• Overrides: precipitation (±mm/month), temperature (±°C), soil pH (±units). Deltas are additive on top of the observed ERA5 / SoilGrids values.
• Result page: side-by-side dual map (baseline left, scenario right) synced on pan and zoom. Right sidebar shows baseline vs scenario score per crop, plus a monthly chart overlaying baseline and override climate lines against the ideal requirement band.
• Demo scenarios: four pre-seeded examples cover drought, irrigation boost, warming, and soil acidification — available immediately without drawing a polygon.
