You built the Breton granite fisherman's house and then its atom kit (v1). The operator loved the house and the kit, but
saw these problems in houses assembled from the kit. Build KIT v2 that fixes them. Start from your v1 kit script:
~/forge-build/forge-assets/jobs/breton-atom-kit-v1/build_kit.py (+ kit.json, materials.json, NOTES.md, visual_review.md,
final.png, sheet.jpg in that folder). The v1 remote dir gex44:/root/fal-author/breton-atom-kit-v1/ and the house dir
gex44:/root/fal-author/breton-stone-house-v1/ (CC0 textures, baked swatches) are READ-ONLY for you: copy what you need.
Your dir: /root/fal-author/breton-atom-kit-v2/ (here: ~/forge-build/forge-assets/jobs/breton-atom-kit-v2/).

Operator's complaints: "windows not the same height between ground and first floor; gutters less polished and pierce the
roof; roof tiles less polished". Also the moss band at the wall foot (Granite_lime_moss_base) had blotchy vertical streaks.
And: "way more diversity in materials, but villages keep coherence".

ATOMS (name: what, [triangle cap])
- window_std: the v1 ground window (0.95 x 1.30 clear opening, 0.38 wall), joinery in Window_frame_paint. Used on EVERY
  full storey. [3000]   shutters_std: the open plank shutter pair for it, Shutter_paint. [1200]
- window_small: 0.50 x 0.70 gable/attic window. [1500]
- window_shop: shop display window 2.0 x 1.9 clear opening, granite surround, timber shopfront frame, fascia board above
  for a name, Window_frame_paint. [3500]
- door_main: v1 door (1.00 x 2.10, door_leaf child hinged left, step), leaf in Door_paint. [4000]
- door_back: plainer rear door 0.90 x 2.10, plank leaf child, smaller step. [2500]
- door_double: tavern/barn door 1.6 x 2.4 with a segmental granite arch, two plank leaves. [3500]
- slate_a..slate_d: real slates (8-14 mm thick, rounded chipped corners, different chips, slight bow), 0.345 x 0.42,
  gauge 0.21. [40 each]   slate_strip_a, slate_strip_b: 4 slates side by side (1.38 m), small per-slate jitter baked in.
  [160]   roof_underlay. ridge_tile (fits 42-47 deg; v1 shape is fine, add mortar bedding). [150]
- verge_board_1m, fascia_1m (painted timber, Window_frame_paint), gutter_1m (half-round zinc, rolled bead edge),
  gutter_bracket, gutter_end_cap, gutter_outlet, downpipe_1m, downpipe_shoe. The gutter must read as polished metalwork
  with brackets visible. [250 each]
- quoin_long, quoin_short (as v1). dormer (as v1 but its window = window_std scaled? NO: build its own 0.85 x 1.10 window,
  dormers are allowed a smaller window). chimney_stack (as v1). lantern (as v1).
- tavern_sign: wrought-iron wall bracket with a hanging painted board (Sign_paint), origin at the wall mount. [1500]
- bench_stone: granite bench against a wall (1.6 m). [400]

SHELF (names exact; the 8 v1 materials stay, Breton_blue_timber/Aged_ivory_frames may stay for unpainted parts):
- Granite_lime_moss (v1, grey), Granite_ochre (warm ochre-brown granite rubble), Granite_pink (Ploumanac'h pink granite
  rubble), Lime_render_white (whitewashed lime render over rubble, some stones showing through): each with Height and the
  SAME tile size and displacement scale as v1 so the wall generator treats them alike.
- Granite_lime_moss_base REDONE: lowest 0.9 m, damp darkening + lichen fading upward, NO vertical streaks, tiles
  seamlessly in X; its V covers exactly 0.9 m.
- Blue_grey_slate (v1) + Green_grey_slate variant.
- Window_frame_paint, Door_paint, Shutter_paint, Sign_paint: neutral light painted timber (white-ish, visible grain and
  slight chipping), list them in paint_slots.
