Lane E round 5 (E2): depot growth — street bin + record-crate stack (consumer-driven)

v2 features are procedural (no forced GLB needs), so E2 is light per Fable's "no
unconsumed entries": two synthetic depot props with clear homes — council-bin ->
procity_street_bin_01 (Lane B street dressing) + milk-crate-stack ->
procity_fit_crate_stack_01 (Lane C floor piles / dig). Both 3k tris, base-origin,
re-normalized to procity names + thumbs, published, verified loading, validate --depot
0 err. Manifest 18 fittings + 10 furniture (28 GLBs). Also noted B3 resolved
(novelty_record 26.5k->8k via E1 bake).

+## Round 5 — E2: depot growth (consumer-driven)
+
+The round-5 v2 features are **procedural** (dig.js riffles generated sleeve art; B's window shader is
+100% procedural; D's roster is spawn logic) — so no forced GLB needs. Per Fable "don't add manifest
+entries no lane consumes", E2 is deliberately light: two already-synthetic depot props with clear
+consumers, re-normalized to procity names + thumbs (both already ≤5k tris, metre-scale, base-origin):
+
+| new id | source | footprint / h | consumer |
+|---|---|---|---|
+| `street/bin` (`procity_street_bin_01.glb`) | `council-bin.glb` (thriftgod_hero, on depot) | 0.57×0.68 m, 1.0 m | Lane B street dressing (towns need bins) |
+| `fit/crate_stack` (`procity_fit_crate_stack_01.glb`) | `milk-crate-stack.glb` (thriftgod_hero) | 0.71×0.72 m, 0.9 m | Lane C record-store floor piles / dig context |
+
+Both 3k tris, verified loading in the vendored GLTFLoader, published, `validate --depot` 0 err.
+Provenance: MeshGod-generated (thriftgod_hero) — synthetic, web-ok. **Note:** also resolved Lane B's
+B3 ask — `novelty_record` (was 26.5k, spiking the busy view) is now 8k via the E1 bake. No speculative
+props added; further depot growth is available on request once C's dig / D's roster name concrete needs.
