baked_tex.ludic reads ludic.base's baked form by hand (render3d uses no package): the LBAK header, the
key ("png_sheets" / "cutouts", the Bakes rows) and the generator version, then the payload -
w, h, channels, depth and the samples for a PNG (the caller frees them as it would a decode), a whole
.dds for a cut-out (tex_load_dds_at: a .dds at an offset). Missing, or another key or version, and the
PNG path runs as before. Compiles with Maroon Lake (game, lab, lab/bake/textures).

Every allocation carries the owner its maker was wrapped in (models, terrain, impostor atlases,
scatter, grass, shadow maps, frame targets, sky, water, game textures, made in a frame), and the
report prints each owner's images and buffers, the 25 largest images and the scatter layers',
streams' and terrain's CPU copies. Nothing drawn changes.

@alloc_ok with its reason on what is made once per resource and kept (textures, programs, samplers,
views, layouts, memory blocks, the pipeline cache in gvk_pipe_build), on resize and swapchain
remakes, on screenshots and dumps, on a world being set up (streams, layers, water, post, bakes), on
loads (gltf_load, skin_load, tex_load*, png_decode, fonts) and on R3D_PROF / drawstats.
gltf_cached's hit path is its own and makes nothing; the miss (gltf_cached_load) is declared.
m4_look_at (now over m4_look_at_xyz) and m4_inverse work on scalars, and cam_update makes no scratch.
Left: lazy first-use starts, error and debug prints, and scratch made and freed each call (churn,
plan 25.3). Compiled (steady, and ludic deps over the game).

The device's textureCompressionBC is asked for and remembered (gvk_has_bc). tex_load_ex prefers a
DX10 .dds with the full chain beside the .png (not for an edge-padded cut-out atlas):
texture_dds.ludic reads BC7 / BC5 / BC4, gpu_tex_compressed makes the image with every level and
no colour-attachment use (a compressed image is only sampled and copied into), and
gvk_tex_upload_blocks copies each level's blocks from one staging buffer. A colour map is BC7
sampled as sRGB, a data map BC7 read as it is. examples/rendering/bc.ludic holds it, in the suite;
ludic.lab's plate carries its .dds (its three shots render at 56-60 dB against the .png's).
ludic-dev test 307/307, no Vulkan SDK in the environment.
