Settings beside the file

A .toml beside an asset says how the file is read: art/hero.png.toml settles art/hero.png. [import.texture] in project.toml is the project's default; a sidecar overrides it key by key.

What landed

• Sidecar. The double extension sorts beside its image in a listing and cannot collide with a scene or a clip named hero.
• Project default. [import.texture] in project.toml; a sidecar overrides one key at a time.
• Every kind. A file's kind comes from its extension: texture, audio, font or model. One resolver reads them all.
• Two keys reach the renderer. filter: "nearest" or "linear". srgb = false for an image that is data, not colour: a normal map, a mask.
• One re-upload. The resolved settings are part of the name a texture is uploaded under, with the file's modification time, so editing a sidecar re-decodes one image.
• Pixels, never sizes. A sprite's extent comes from the image header, so a headless run computes the same world as a windowed one and import settings stay out of the digest. Downscaling for a phone is an export key.

# art/hero.png.toml
filter = "nearest"   # pixel art, drawn crisp instead of blurred
srgb = true          # false for a normal map or a mask, which carry data

# project.toml
[import.texture]
filter = "nearest"

Written but not wired: repeat, mipmaps, anisotropy, premultiplied alpha, and an Import section in the editor. On the roadmap; Import settings is the manual.
