Merge pull request 'Editor mode model: mobile Fixtures/Plants/Journal/Assistant bar (#99 )' (#110 ) from feat/editor-modes into main

Address editor-mode review: mode↔focus↔rail syncing
Gadfly on #99, the real ones — all in the mode/focus/rail interplay: - (3 models) Closing a journal/assistant rail while a bed was focused hard-set mode='fixtures', docking the OBJECT palette inside the focused bed with the seed tray unreachable. Derive it: closing a panel returns to Plants if still focused, else Fixtures. The canvas-mode effect now also follows UN-focus (plants→fixtures) and won't override a panel mode. - (2 models) Plants mode on a focused non-plantable object (reachable via a ?focus= deep link) showed the misleading "tap a bed" hint and no way out on mobile. Now it says what's wrong and offers Done (exit focus). - Selecting an object leaves a panel mode, so closing the inspector can't strand the bar on Journal/Assistant with nothing open. - Tapping Fixtures steps out of a focused bed (you're arranging again). - Viewer mode bar drops Fixtures/Plants (a viewer can't place anything), leaving Journal + Assistant. - Safety: if the assistant capability flips off live while it's the active mode, fall back to a canvas mode and close the orphaned chat rail. Maintainability: extracted the shared seed-tray + Done + Clear cluster into PlantPlacementTools (was duplicated between the desktop focus toolbar and the mobile Plants strip); DEFAULT_MODE const replaces the twice-hardcoded 'fixtures'; selectMode reads the reactive railTab, not getState(). Verified live at 390px: focus a bed → Plants; open journal → close → back to Plants (tray), not the Fixtures palette; tap Fixtures → exits focus.

 ## Decisions

 - **Placement model:** freeform plops (not a square-foot grid), scaled by real plant spacing. Grid snapping may come later as a toggle.
- **Spacing is a plant-to-plant rule, so bed edges get half of it.** A bed edge is not a competitor for soil, light or water, so the outer row owes it half the spacing rather than a full one. `FillRegion` centres its lattice accordingly, and lets a plop — a *clump* three spacings across — cross the edge by up to half a spacing so its outermost plants land at that half-spacing. The rule, the square-foot-chart arithmetic behind it, and the failure mode it prevents are written out once in `hexCenters`; #75 is what getting it wrong looked like.
+- **A fill is one of two operations (#77).** A plop is a *clump*, not a plant, which is the right primitive for SKETCHING ("a few plops of garlic in a corner") but can't draw a real planting — a filled bed comes out as ~15 blobs, not 8 rows of garlic. So `FillRegion`/`FillNamedRegion` take a `FillLayout`: `clump` (default; plop radius 1.5×spacing, ~7 plants each — quick coverage) or `grid` (radius spacing/2, pitch = spacing, ONE plant per plop — a layout you could plant from). Surfaced on `POST /objects/:id/fill` (`layout`) and the agent's `fill_region` (`mode`). Same centered `hexCenters` lattice for both, but BOTH the plop radius (`plopRadiusFor`) and the edge inset (`edgeInset`) differ by layout: a grid plant sits at the plop's centre, so it insets a half-spacing; a clump's plants reach its rim, so it insets radius-less-a-half and overhangs the edge by that half — reusing the clump formula for grid would inset by zero and plant flush on the edge. A grid-filled bed approaches the low-hundreds-of-plops the SVG budget was sized for, which the semantic-zoom tiers already anticipate.
+- **Spacing is a plant-to-plant rule, so bed edges get half of it.** A bed edge is not a competitor for soil, light or water, so the outer row owes it half the spacing rather than a full one. `FillRegion` centres its lattice accordingly, and lets a plop — a *clump* three spacings across — cross the edge by up to half a spacing so its outermost plants land at that half-spacing. The rule, the square-foot-chart arithmetic behind it, and how it differs by layout are written out once in `edgeInset` (which `hexCenters` then honours); #75 is what getting it wrong looked like.
 - **Stack:** Go 1.26.x backend, module `gitea.stevedudenhoeffer.com/steve/pansy`; React + TypeScript + Vite + Tailwind frontend, production build embedded via `embed.FS` → one static binary (`CGO_ENABLED=0`).
 - **Users:** multi-user with ownership. Users own gardens; a garden can be shared with other users as viewer (read) or editor (edit content). Owner additionally shares/deletes. The first registered user is `is_admin` (set race-free inside the INSERT); admin gates instance-wide Settings (`requireAdmin`), the only thing that reads that flag.
 - **Auth:** OIDC-first (Authentik is the primary IdP), local argon2id passwords as an optional fallback.
 - **Instance settings (#79):** admin-editable, instance-wide config in a single-row `instance_settings` table — pansy's first DB-stored *instance* state (everything else hangs off a garden/object). Today it holds the agent model + on/off; **secrets never move here** — `OLLAMA_CLOUD_API_KEY` stays in the env so it doesn't land in backups or the undo history. Precedence: Settings value → env → default. The live agent Runner sits behind an `atomic.Pointer` in the API layer (`agentHolder`) with its routes always registered, so a settings change swaps it with no restart and no race against in-flight requests; `/capabilities` reads that pointer, so it reports what's live rather than what was configured at boot. The model/registry knowledge lives in one leaf package (`internal/agentmodel`) that both the runner and the settings validator import — agent imports service, so it can live in neither.
+- **Seed-packet capture (#81):** photograph a packet → a *vision* model (separate `vision_model` setting) reads it into structured fields via one-shot `majordomo.Generate[SeedPacket]` — NOT an agent loop, so the extraction can't touch the garden; it only reads a picture and returns data. The image is normalized to JPEG at the upload boundary (`internal/imagenorm`: decodes HEIC/webp/png/jpeg, since majordomo's stdlib media path can't do HEIC — the iPhone default). The hard part is **catalog matching, not OCR**: a wrong auto-match splits a variety's seed-lot history across duplicate rows, so the service NEVER auto-creates — it surfaces ranked candidates (`matchPlants`) and the user confirms, then `CreateFromPacket` makes the plant (new or existing) + the lot. Plants/lots aren't in the undo history (they're catalog/inventory), so there's no change set to wrap. The extractor is injectable on the service (`WithPacketExtractor`) so the whole path tests hermetically against majordomo's `fake` provider.
 - **Agentic future:** integration with majordomo/executus via typed Go tools (`llm.DefineTool[Args]`) wrapping the same service layer the REST API uses — not MCP/OpenAPI.

+- **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.

 - **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.

 The assistant acts without asking first, which is only reasonable because every turn is one undoable change set — see the History panel in the editor.
