Burgundy border shrub (`burgundy-shrub-study/desktop.glb`, `mobile.glb`), updated October 3, 2026: Rico Cilliers / Poly Haven Shrub 04, CC0-1.0. https://polyhaven.com/a/shrub_04 and https://polyhaven.com/license . Original folded leaf/twig geometry and photographed PBR/alpha maps form a generic ornamental mound; the green diffuse is explicitly graded burgundy. Both tiers retain 29,820 triangles with one material, three 1024 px high maps or three 512 px standard maps. Source fragments and authored branching limits are recorded in CREDITS.md and manifest.json. Geometry costs 3.38 times the original desktop; no species certification or mobile performance claim.

Calibrated Gray Ledger Stone maps (`teamc-surfaces/stacked_stone_wall_grey`), October 3: Dimitrios Savva / Poly Haven Stacked Stone Wall, CC0. https://polyhaven.com/a/stacked_stone_wall and https://polyhaven.com/license . Existing gray grade retained as the input to reviewed linear contrast/gain adjustment; OpenGL normal XY0.25 baked and renormalized. Source extent2m, calibrated application repeat1.2m. Original source/runtime bytes are preserved externally; material.json and CALIBRATION.json record hashes and processing. No manufacturer identity is claimed.

Original folded leaf/twig geometry and photographed PBR/alpha maps adapted into an unspecified compact ornamental. Desktop1024 and standard512 maps share16,226-triangle geometry. It is a separate catalog option, not a clipped-shrub replacement or botanical certification. CREDITS.md and manifest.json record source scale, leaf size, packed source hash and actual tier costs.

White flower clump lower border (`white-flower-clump-study/desktop.glb`, `mobile.glb`), updated 2026-10-03: retained PondTools curved corolla/stalk and leaf-contour geometry, cgbookcase Green Leaf 10 photographed interior PBR maps (CC0), https://www.cgbookcase.com/textures/green-leaf-10 . Generic unnamed ornamental study, not a scanned or identified species. Earlier ownership/source credits remain in white-flower-clump-study/CREDITS.md; exact tier/source hashes and bounds are in manifest.json. Proprietary Pool Studio images were used only for visual comparison.

Calibrated Herringbone Pavement maps (`teamc-surfaces/herringbone_pavement`): Charlotte Baglioni / Poly Haven, CC0. https://polyhaven.com/a/herringbone_pavement and https://polyhaven.com/license .
