+- **State:** TanStack Query for all server state (editor keyed on `gardens/:id/full`; optimistic mutations with version-conflict rollback). One small Zustand store for ephemeral editor state only: viewport, selection, focused object, active tool, in-flight drag, and the mobile `mode`.
+- **Mobile-first editor: one primary mode (#99).** On a phone the canvas is the whole screen; a bottom mode bar switches which tools dock beneath it — **Fixtures** (the object palette), **Plants** (the seed tray, shown once a bed is focused; focusing a bed puts you in this mode), **Journal**, **Assistant** (the last two open the rail sheet; Assistant is hidden with no model). This replaces the old phone layout where a stacked control column shoved the garden into a corner. Desktop keeps its side-column layout (the mode bar is `md:hidden`) and treats `mode` as an inert hint. History stays reachable as a rail sub-tab rather than a fifth primary mode.
 - **Editor components (`web/src/editor/`):** `GardenCanvas` (svg root + viewport g), `useViewport` (use-gesture pan/zoom/pinch), `ObjectShape`, `PlopMarker` (semantic-zoom branching), `Palette` (drag-to-place object kinds), `EditorRail` (the one side panel), `Inspector`, `HistoryPanel`, `PlantPicker`.
 - **One rail, tabs inside it.** The inspector, history, journal and assistant all want the same strip of screen; rather than each bolting on its own chrome they are tabs in `EditorRail` — so the canvas is one width instead of a different width per panel, and adding a panel is adding a tab. Selecting an object switches to the Inspector tab automatically, so the rail is never something you operate before you can edit; on a phone the same tabs render in the bottom sheet the inspector already used. Pure geometry helpers (local↔world transforms, unit formatting) in `web/src/lib/geometry.ts`, unit-tested.
