Website side of the new skin options. Needs TF-Minecraft/ArmourShop#44 on the server to apply the new kinds and animations.

3D bows and crossbows (bow_3d, crossbow_3d)

• One texture plus model, pull_0_model, pull_1_model, pull_2_model (and charged_model for crossbows).
• All files together, .mcmeta included, must fit in 61,440 bytes, the same for every rank. The per-rank texture+model cap doesn't apply.
• The preview has Standby / Pull 0–2 / Charged buttons. Review sheets show standby, full draw, and charged for crossbows.

Animated textures

• Optional {field}_mcmeta beside any PNG field except armour layers, up to 2 KB, checked against Minecraft's frame rules.
• Fixed-size slots accept a grid of frames of that size.
• Stored as <png>.png.mcmeta and listed for the plugin. Previews animate; static renders use the first frame and are labelled "animated · N frames".

Skin targets come from one shared list, shared/skins/base_sets.json, read by both backend and frontend.

• New targets: wands, mage blades, longswords, greataxes, battle standards (3D only), pickaxes, shovels, fishing rods, instruments. Every non-armour target can also be 3D.
• New armour single sets: leather, the six mage schools, and light, dark and wild mage.

Upload flow redesign

1. What are you skinning? Grouped, searchable tiles.
2. Style: only the styles that item supports. Styles locked for the player's rank show the rank name.
3. One card per file, each with an optional animation slot.

Validation:

• Backend skins tests: 326 passed. The one failure, test_ban_events::test_times_round_trip…, also fails on a clean main locally.
• Frontend: lint, tsc, format check, npm test (2393 passed) and npm run build all pass.
• The render bundle builds.

📝 Summary

Summary by CodeRabbit

• New Features

  • Added 3D bow and crossbow skin uploads, including draw stages and charged crossbow views.
  • Added animated texture support through optional .png.mcmeta files, with playback in previews and first-frame thumbnails.
  • Added searchable skin targets, standalone armour sets, entitlement-aware choices and clearer upload guidance.
  • Added animated 3D and flat-texture previews, review-sheet frame counts and expanded asset downloads.

• Documentation

  • Updated skin, armour and ArmourShop documentation with new formats, limits and animation guidance.

This change adds ranged 3D bow and crossbow uploads, optional animated PNG metadata, and standalone armour targets. It updates upload validation, storage, preview rendering, owner-file delivery, entitlement handling, and documentation.

Changes: Skin catalogue and target rules

Layer / File(s)	Summary
Shared catalogue and target access shared/skins/base_sets.json, backend/src/skins/base_sets.py, frontend/lib/skins/baseSets.ts, frontend/lib/skins/kindAccess.ts, backend/src/skins/naming.py, frontend/lib/skins/entitlementsDev.ts	A shared catalogue now defines skin targets, permitted kinds, armour options, labels, and file-size limits. Backend and frontend helpers load the catalogue and resolve target types, labels, and kind access.
Target selection and upload form frontend/app/components/skins/UploadForm.tsx, frontend/app/components/skins/SkinTargetPicker.tsx, frontend/app/components/skins/KindPicker.tsx, frontend/app/components/skins/FileSlot.tsx, frontend/app/components/skins/KindHelp.tsx, frontend/lib/skins/sizes.ts	The form now selects a target and skin kind, supports standalone armour sets and ranged 3D file fields, and accepts optional animation metadata for supported textures. It validates models, textures, entitlement access, and ranged 3D file totals.
Backend submission and storage backend/src/skins/submissions.py, backend/src/skins/storage.py, backend/src/skins/animation.py, backend/src/skins/size_limits.py, backend/src/api/skins_routes.py	Backend validation accepts ranged 3D submissions and standalone armour tiers. Storage validates and writes model, PNG, and .mcmeta files. Applicable size checks include metadata bytes, and owner-file serving permits .png.mcmeta files.
Previews and owner-file display backend/src/skins/preview_3d.py, backend/src/skins/review_sheet.py, backend/src/skins/thumbnail.py, frontend/app/components/skins/ModelPreview.tsx, frontend/app/components/profile/SkinShowcase.tsx, frontend/lib/textureAnimation.ts, frontend/lib/skins/animatedTexture.ts, frontend/lib/skins/ownerFiles.ts	Ranged 3D views use stage-specific models. Animated textures use scheduled frames in previews and first frames in thumbnails and review sheets. Owner-file mappings include ranged models and supported animation files.
Validation coverage and supporting updates backend/src/skins/test_ranged_3d_and_animation.py, backend/tests/test_skin_asset_lifecycle.py, frontend/app/components/skins/UploadForm.test.tsx, frontend/lib/skins/*.test.ts, frontend/lib/textureAnimation.test.ts, docs/docs/cosmetics/*, docs/docs/integrations/armourshop.md, frontend/app/components/wiki/stationTextureAnimation.ts	Tests cover catalogue data, upload validation, storage, animation handling, previews, and file delivery. Documentation describes the new upload kinds, armour target rules, metadata files, and ArmourShop handling. Station texture animation now delegates to the shared animation implementation.

Merge Risk: 🔵 Low · up to 4f456

Bow and crossbow 3D skins and animated textures work end to end, and the server enforces the correct rules. A few upload-form checks and previews are inconsistent with the server. Some animated uploads show a preview error, and some are rejected only after submission instead of up front. These are minor issues for the uploader, and the change can merge with follow-up fixes.

🟡 Minor · Count the texture .mcmeta in the frontend 3D pair budget. · sizes.ts:183-219

frontend/lib/skins/sizes.ts:183-219
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Count the texture .mcmeta in the frontend 3D pair budget.

The backend assert_pair now adds texture_mcmeta (and {tier}_helmet_texture_mcmeta) to each texture + model pair. The docs also state that the .mcmeta counts toward the budget. The frontend assert3dPairBudgets still checks only files.texture and files.model. Assume an item_3d, gun or 3D-helmet upload with an animation sits just under the pair cap. The client check then passes, and the API rejects the upload with a 400 after the user submits. Add the matching _mcmeta file to assertPairBytes.

Proposed change (sketch)

// assertPairBytes(texture, model, cap, label, mcmeta?) → add (mcmeta?.size ?? 0) to the total
assertPairBytes(files.texture, files.model, cap, kind, files.texture_mcmeta);
// gun:
assertPairBytes(files.texture, files[stem], cap, `gun/${stem}`, files.texture_mcmeta);
// armour 3D helmet:
assertPairBytes(files[`${t}_helmet_texture`], files[`${t}_helmet_model`], cap, `armor_set/${t}_helmet`, files[`${t}_helmet_texture_mcmeta`]);

Update assertPairBytes and each call in assert3dPairBudgets to include the
corresponding texture .mcmeta file size in the pair total: files.texture_mcmeta
for item_3d and guns, and files[`${t}_helmet_texture_mcmeta`] for 3D armour
helmets. Preserve the existing optional-file behaviour by treating a missing
.mcmeta file as zero bytes.

- Around line 555-562: Update the animated frame mapping in ModelPreview so a
fully transparent frame does not abort preview creation: handle the expected
“Texture has no opaque pixels” failure from buildExtrudedItemGroup by using an
empty THREE.Group for that frame, while preserving normal extrusion, visibility,
and root.add behaviour for non-transparent frames.

Review comments at @frontend/lib/textureAnimation.ts:
- Around line 132-178: Update parseTextureAnimation to strip one leading UTF-8
BOM before JSON.parse, require the top level to contain only “animation”, and
reject unsupported keys inside the animation object while preserving existing
validation. Replace the local MCMETA_MAX_BYTES definition with the shared export
from skins/baseSets so the frontend uses the configured limit.
