 # Changelog
 
+## v0.23.1 — 2026-09-20 08:42
+- **Toasts repositioned to the map's right edge (ISS-039).** The `.toasts` stack was `position: fixed` at the viewport bottom-right, overlapping the 280px right pane; its `right` changed 12px → 292px (= 280px right pane + 12px inset) so it now sits flush against the map's right edge with the same 12px margin. No JSX/endpoint changes — all positioning lives in that one CSS value
+- Tests: e2e wording only — `toasts.spec.ts` header comment, test title, and toast visibility assertion message updated from "bottom-right" to "map right edge / clear of the right pane"; no position assertions added (none existed), suite unchanged at 41 tests in 12 files
+- Verified: `tsc --noEmit` clean; unit suite green locally (288); `npx playwright test --list` = 41 tests in 12 files; e2e not run locally by design — CI verifies against an isolated stack

 ## v0.23.0 — 2026-09-20 08:25
 - **Refuel-to-full row moves to the left pane (ISS-035).** Refueling a grounded plane is "anything with our plane", so it belongs in the left pane next to Relocate, not as a market row on the right. The `.market-row` JSX (`market-refuel-none` "All tanks full." span / `market-refuel-plane` select of grounded planes labeled `{planeName} — {fuel}/{maxFuel} L`, `market-refuel-cost` preview, `market-refuel` button → `POST /api/planes/{id}/refuel`) moved verbatim from the Market section in `components/RightPane.tsx` into a new "Refuel" `<section data-testid="refuel-section">` in `components/LeftPane.tsx`, inserted between Relocate and Time. Its state (`refuelPlaneId`) + derived values (`refuelable`, effective-selection `refuelPlane`, `refuelCost`) moved with it, reusing LeftPane's existing `grounded` list; busy gating rewired from RightPane's `busy` to LeftPane's own `useGameAction` instance (`actionsBusy`). Testids kept byte-identical so all e2e locators are unchanged. The per-package "Refuel" button in the On board section (`refuel-for-{pkg.id}`, mode 'forFlight') is a different feature and stays put; exported helpers `slotsUsedFor` / `loadEligiblePlanes` untouched
 - Tests: e2e — `right-pane.spec.ts`: the market test keeps its buy/sell assertions, renamed to reflect that the refuel row now renders inside `[data-testid="left-pane"]` (asserted before the click); functional cash/tank assertions unchanged; the for-leg test's title/comment updated from "market button" to left pane. `panes.spec.ts`: first test gains structural assertions — Refuel heading + `market-refuel` visible in the left pane, both absent from the right pane (same present-in-left / absent-from-right pattern as On board). No unit-test changes (suite stays at 288)
