Reading the landscape

Solid border — panel-validated evidence
Dashed border — at edge of current evidence
Green line — aligned descriptors (shared chemistry or process)
Red dashed — opposing descriptors (incompatible pathways)
Tap any territory to explore it. Tap a second to compare. Drag to reposition.

How to use this landscape

1
Tap any territory to open it. You will see its chemical drivers, which process produces it, what leaf it needs, and how to brew for it. Lines appear connecting it to related territories.
2
Green lines connect aligned territories — descriptors that share chemistry or can come from the same process pathway.
Red dashed lines connect opposing territories — descriptors that require incompatible processes.
3
Tap a second territory to compare the two side by side — process, leaf, brew requirements and their relationship to each other.
4
Drag any territory to reposition it within its domain area on the map. Connection lines redraw as you move. Territories stay within their quadrant.
5
Tap the active territory again to deselect and return to a clean view.
6
→ Build a pathway — the link at the bottom of any territory detail takes you to the Flavour Logic Board with that descriptor pre-selected.
7
Dashed border on a territory means it sits at the edge of current evidence — observed in traditional practice but not yet formally panel-validated.
Research basis: tap "+ Research basis" at the bottom of the page.
