Expanded fleet cards for Town Survival, Farm Survival, and Bus Depot Survival can display “Current map: TranZit” beneath the correct Survival heading. The line suggests a different map or mode even when the reported engine map matches the server's selected variant.
Production verification on October 12, 2026 found both Town lobbies registered with map_slug: town, configured map: zm_transit, and observed last_map: zm_transit. Farm and Bus Depot have the same engine map with their respective variant slugs. This evidence does not indicate an engine-map change; the engine identifier alone cannot distinguish the variants.
Cause and scope
src/lib/map-aliases.ts:38-61 defines TranZit, Town, Farm, and Bus Depot as separate selections sharing zm_transit.
src/lib/ui/server-labels.ts:9-16 resolves a canonical map by its first matching entry, translating zm_transit to TranZit without variant context.
src/lib/fleet-overview.ts:69-90 uses the selected variant when it matches the observed engine map. src/routes/+page.svelte:575 passes that resolved name as the card heading.
src/lib/ui/components/ServerCard.svelte:79-80 independently applies the generic lookup and compares the resulting display text with the heading. Town Survival and TranZit differ, so :154-160 renders the misleading line. Empty compact cards hide it, explaining why only occupied Town lobbies showed it in the reported screenshot.
The fleet list and server-detail scoreboard already use the variant-aware fleet identity. A related fallback also needs coverage: when the variant is unknown, the generic lookup silently chooses TranZit. Conversely, an actual change to a different engine map currently changes the fleet identity and removes the old selection's launch shortcut; preserve that behavior.

Fix
Use consistent, variant-aware map resolution for the fleet card heading and any Current map/Last map context. Do not interpret different friendly labels for the same selected engine map as a map change.
For known Town, Farm, and Bus Depot selections reporting zm_transit, retain their Survival names and omit the redundant TranZit line. Keep an explicitly selected TranZit server named TranZit.
When a shared engine map has no recognized variant, show an explicit ambiguous/raw-map fallback rather than asserting that the mode is TranZit.
Preserve genuine engine-map changes: display the observed map and keep the previous selection's launch shortcut unavailable. Do not force the configured Survival name onto a different reported engine map.
Add rendered-card regressions for all four zm_transit selections, custom server names with stored variant metadata, missing/unknown variants, compact versus expanded cards, stale observations, and a real map change such as zm_transit → zm_tomb. Verify reactive updates and consistency with fleet list/detail labels.
Validation
Reviewed main at 272055a. Reproduced the Town label in a real browser against a disposable fixture and verified that its detail scoreboard says Town Survival. Exercised map resolution for Town, Farm, Bus Depot, TranZit, Buried, an unknown variant, and a change to Origins. The two existing fleet-overview/server-card suites pass all 18 tests but do not cover the contradictory map line.

Expanded fleet cards for Town Survival, Farm Survival, and Bus Depot Survival can display “Current map: TranZit” beneath the correct Survival heading. The line suggests a different map or mode even when the reported engine map matches the server's selected variant.
Production verification on October 12, 2026 found both Town lobbies registered with `map_slug: town`, configured `map: zm_transit`, and observed `last_map: zm_transit`.

**Cause and scope**
- `src/lib/map-aliases.ts:38-61` defines TranZit, Town, Farm, and Bus Depot as separate selections sharing `zm_transit`.
- `src/lib/ui/server-labels.ts:9-16` resolves a canonical map by its first matching entry, translating `zm_transit` to TranZit without variant context.
- `src/lib/fleet-overview.ts:69-90` uses the selected variant when it matches the observed engine map. `src/routes/+page.svelte:575` passes that resolved name as the card heading.
- `src/lib/ui/components/ServerCard.svelte:79-80` independently applies the generic lookup and compares the resulting display text with the heading.

Validation is rendered-component coverage; the reused browser fixture had no Town cards available, so it was not counted as a browser reproduction of this fix.

**Checklist**
- [x] **One map resolver.** ServerCard now uses `fleetIdentity`, with game/variant/mode metadata passed by the fleet page.
- [x] **All four selections.** Rendered-card tests retain Town/Farm/Bus Depot Survival and explicit TranZit labels without redundant map context.
- [x] **Ambiguous fallback.** `server-labels.ts:9` returns the raw engine map plus “variant unknown” when multiple selections share it.
- [x] **Real changes.** Tests switch from `zm_transit` to `zm_tomb`, show Origins, and remove the old launch shortcut.
- [x] **Compact/stale behavior.** Rendered tests retain compact empty cards and useful Current/Last wording.
- [x] **Reactive coverage.** `ui-server-card-maps.test.ts` exercises custom names, stored/missing/unknown metadata, stale/offline observations, reactive changes and shared card/list/detail labels.
