The arrow-key nudge handler existed but only ever acted on a POINTER
selection, and nothing could select without a mouse — so the feature was
unusable by exactly the keyboard users it's for. This is the scoped first
slice: give the canvas a keyboard path in, and fix the Modal focus trap that
every destructive confirmation goes through.
Canvas:
- The <svg> gets role="application" + an aria-label describing the controls,
and a <title> naming the garden — a screen reader now announces an
interactive canvas rather than an empty graphic.
- Each object <g> is a focusable role="button" with an aria-label (name +
kind) and aria-pressed reflecting selection. Enter/Space selects it — the
step that was missing — which makes the existing arrow-key nudge reachable.
- A :focus-visible CSS rule draws a dashed accent ring on keyboard focus (and
NOT on a mouse click, which is the point of :focus-visible). CSS rather than
React state because onFocus on an SVG <g> is unreliable, and a CSS rule
cleanly overrides the shape's inline stroke.
Modal (blast radius: DeleteGarden/ClearBed/DeletePlant/DeleteSeedLot/Share):
- Tab is trapped inside the dialog and wraps at the ends, instead of walking
out into the page behind the backdrop.
- On close, focus returns to the element that opened the dialog rather than
landing on <body>.
Verified live against the built binary with real keyboard input: Tab focuses
an object (SVG <g tabindex> genuinely takes focus), Enter flips aria-pressed
false→true, the focus-visible dash renders (computed stroke-dasharray "5px,
4px"), the dialog traps focus through 5 Tabs, and Escape closes it and
restores focus to the opener.
Follow-ups noted, not done here: object dimensions in the aria-label (needs the
garden's unit context this component doesn't hold), roving-tabindex between
plops inside a focused bed, and the EditorRail tablist semantics.

Implements the Pansy v1 scaffold (epic #20, phase 0).
#1 Backend: Go module (pure-Go, builds with CGO_ENABLED=0), env config,
gin server with slog + recovery + /api/v1/healthz, modernc SQLite store
with WAL/busy_timeout/foreign_keys pragmas, embedded numbered-migration
runner, full initial schema (users, sessions, gardens, garden_shares,
garden_objects, plants, plantings), domain structs + sentinel errors,
graceful shutdown.
#2 Frontend: Vite + React 19 + TS (strict) + Tailwind 4 + TanStack
Router/Query, typed /api/v1 fetch wrapper (ApiError carries status +
body so later issues can read 409 conflict rows), dev proxy /api -> :8080,
responsive app shell with stub pages for all five routes.
#3 Single binary: //go:embed of the web build with a committed placeholder,
SPA fallback (deep links, immutable asset caching, JSON 404 for unmatched
/api and missing assets), Makefile (web/build/dev/test), README quickstart
+ env var table.
Verified: go build/vet/test clean (CGO off); binary migrates idempotently and
serves healthz; web tsc + build clean; integrated binary serves the SPA, deep
links, and correct cache headers; app mounts and navigates all five routes at
desktop and 375px widths.
