feat(maps): layout select, scale tiers, and the City Streets generator#148
Merged
Conversation
- MapLayout decoupled from Environment (auto/dungeon/cavern/wilderness/ city; building reserved for PR 2). Auto maps Urban to city and Any to dungeon; plain dungeons are directly selectable in any environment - MapScale tiers (Skirmish/Standard/Large/Massive) replace the width/height picker on both pages; dimensions derive per layout with +/-8pct seeded jitter; engine ceiling raised to 60x45; width/height remain exact overrides for legacy links and JSON callers - generateCity: full-run street lattice, solid building masses with street-facing locked doors (UVTT portals), plazas/markets/groves, gate + far-ward + landmark zones, connectivity by construction - Grim city flavor pools (Gallows Corner, Execution Square, ...) - URL params ml/ms on both pages; legacy mw/mh parse and round-trip; scale-mode links serialize ms so regeneration replays jitter draws (map-history stubs likewise) - Export pixels-per-grid auto-scales to the 4096px raster cap - Fourth-wall note: third accepted grid-stream break; all hash pins re-recorded (env Any + exact dims pin proves legacy-mode continuity) Closes #145

PR 1 of milestone #8 Map Layouts & Scale (spec:
docs/superpowers/specs/2026-07-19-map-layouts-design.md). Closes #145.What changed
width/heightsurvive as exact overrides.msand history stubs replay scale mode — regenerating with explicit dimensions would skip the draws and change the grid. Caught by TDD before it shipped; legacymw/mhlinks parse and round-trip untouched.min(70, floor(4096/longest side))feeds PNG and the UVTT resolution block alike — grid alignment exact at every size (Massive ≈ 68 px/cell).Compatibility
Third accepted grid-stream break (jitter draws lead the stream; Urban seeds re-layout as cities). All 9 hash pins re-recorded — including an
environment: 'Any'+ exact-dims pin whose hash is unchanged from the previous contract, proving legacy-mode draw continuity.Tests
11 new layout/scale tests + scale-mode history round trip; dungeon-shaped fixtures moved to explicit
layout: 'dungeon'; freeze file now pins 9 configurations. Full suite 657 passing; typecheck, lint, build clean. Verified on the static build: Standard city from a share link with grim zone names, Massive city at 60×43, width inputs gone.
