## Structure

- /plants/<key> — one tracker page per species/variety: low/median/high per form factor, per-vendor tables, daily price history
- /types/<genus> — one page per genus (dionaea, drosera, sarracenia, nepenthes, pinguicula, utricularia, cephalotus, heliamphora, darlingtonia, byblis, drosophyllum, aldrovanda, genlisea, roridula, brocchinia)
- /vendors/<id> — per-vendor catalog stats and market positioning
- Data tables are semantic HTML; every page states its last-updated date.
- Prices on a plant page are grouped by form factor and must not be compared across groups.
