// PROCITY Lane C — type theming. Every CITY_SPEC shop type gets a distinct interior recipe so a
// `record` shop instantly reads different from a `toy` shop the moment the door opens.
//
// LANE_C says "import SHOP_TYPES from core/registry.js" — Lane A hasn't landed registry.js yet, so
// this lane stays FULLY STANDALONE: the canonical recipes live here. When registry.js exists, Lane F
// can call `mergeRegistry(SHOP_TYPES)` to let authored registry data override any field. No hard
// dependency, so the test page runs with zero other lanes.

// Fitting `kind`s referenced below must exist in fittings.js FITTINGS registry.
// Zones the layout placer understands: 'window' (front, by glazing), 'aisle' (centre rows),
// 'wall' (perimeter, uses wall-slots), 'centre' (free-standing island), 'counter' (till corner).
//
// Recipe fields:
//   archetypeBias : weighted room-shape preference (keys of shell.ARCHETYPES) — 'auto' picks from here
//   wallpaperBias : biased pick from web/assets/gen/wall-*.jpg (names without prefix/suffix)
//   floorBias     : biased pick from carpet/lino/board floor names
//   clutter       : 0..1 density multiplier (some shops crammed, some sparse)
//   counterPos    : 'door' | 'forward' | 'corner' | 'back' — where the till lives
//   fittings      : the mix. Each {kind, zone, min, max, priority}. Counts scale with clutter+area.
//                   priority: higher = more essential; flood-fill removes low-priority first if the
//                   door→counter path is ever blocked. Counter is always highest.
//   stockKind     : what stock.js renders into this shop's carriers
//   signFlavour   : seeded inside signage strings, themed
