impostor_from_baked / impostor_refill read a bundle of two DX10 .dds (albedo, normal: BC7_UNORM, every level) through tex_load_dds_at and gpu_tex_compressed - no gpu_tex_mips - and check each is the impostor's size; sampled as a painted atlas is (clamped, no anisotropy). No BC on the GPU, or a bake that does not fit, and the caller paints RGBA8 and makes mips as before; the fog re-open reads the BC7 file again. The handles and every draw are unchanged. Compile-only: nothing run. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

**Bakes you can look at, and three more of the renderer's textures read from one.** `ludic.lab` writes
|
|
raw 8-bit pixels (1 to 4 channels) as a PNG (`lab_png_write`, `png_write.ludic`, importable alone with its
|
|
own `LabPngState`) and turns float textures into honest previews (`png_convert.ludic`: R32F min..max as
|
|
grey, RG16F as red and green x255, HDR RGBA16F as x/(1+x) then sRGB). `ludic.render3d` takes three bakes
|
|
the game names (`bake_load.ludic`) and makes each as before when one is missing or stale: an impostor's
|
|
atlases as BC7 with their baked mips, through the compressed upload (`impostor_from_baked`,
|
|
`impostor_fill_bc7`; a fog opening past its cards reads the bake again instead of painting), the sky's image-based light at the start yaw per prefilter width (`sky_baked_in`; any other
|
|
turn of the sky is convolved), and the grass carpet (`carpet_from_baked`, `carpet_bytes`).
|
|
`impostor_from_bytes` returns null, keeping nothing, when the bytes are not the impostor's shape.
