Here's our biome list. The canonical catalog lives in `art.md` § Biome moods catalog (refined in the Phase 3 procgen spike), with the playable ordering set by `plan.md`'s locked progression chain.

## The progression chain (biome-gated)
`plan.md:81` locks the order players move through:

**pine forest → suburban ruins → industrial outskirts → burnt-out town center → cold-war military bases & silos → irradiated downtown core**

## Full biome moods catalog (`art.md:54`)

| Biome | Mood / aesthetic |
|---|---|
| **Pine forest / boreal** | Naturalistic starter — light overcast, soft danger (chain start) |
| **Meadows** | Chill / restorative — golden light, gentle wildlife, faded remnants (Valheim Meadows) |
| **Cathedral forest** | "Cathedral solitude" — mossy oaks, fog, **home for wonder anomalies** (shorthand: *Dagobah*) |
| **Suburban ruins** | Early-reclamation UK cul-de-sacs — buddleia, rusting cars, streets still readable |
| **Swamps** | Foggy/wet, mutant density, **anomaly cluster pocket** — pulled back from full horror (STALKER) |
| **Industrial outskirts** | Abandoned factories, rail yards, mechanical hazards |
| **Burnt-out larger cities** | Skyscraper canyons, scorched concrete (TLOU/I Am Legend) |
| **Small surviving cities** | Fortified UK communities — grey, utilitarian, NPC trade + quests (Children of Men) |
| **Military zones (silos/bases)** | Cold-War installations — settings, not an anomaly archetype |
| **Verdant ruin POI** | Time-dilation overgrowth — landmark-scale anomaly signal |
| **Irradiated zones** | Hottest rads, biggest mutants — high-tier, not the singular endgame |

## Two things worth flagging
- **"8 biomes" vs 11 entries.** `plan.md:124` (audio philosophy) refers to *"each of 8 biomes gets its own audio personality,"* but the catalog above lists 11. Some of these are POI/set-piece types rather than full biomes (Verdant ruin POI, arguably Meadows and Military zones). The "8" figure hasn't been reconciled against this catalog — might be worth pinning down which entries are first-class biomes vs. POIs.
- **Displaced zones** (Japanese-neon / Kent-field americana) are a *cross-cutting subtype* in `lore.md`, not a row in this table — and they're tangled in an open tension (`tensions.md:86`) over whether Big Slum Alley / Miami Vice City anchor surviving-cities or displaced zones.

Want me to reconcile the "8 biomes" count, or dig into the displaced-zones tension?
