Owner

The archive was showing the second-to-last version of the prototype.

main sat three commits behind the actual finale: the texture backdrop with its
procedural fallback (4691cf6), the moiré/milk fix (420edbb), and the mip pyramid,
adaptive milk and Regular/Clear/Identity switch (137a342). All three lived only in
glass-pr1, pushed but never merged — so anyone opening this repository to see what
eight iterations achieved saw the wrong thing. The project chronicle already recorded
one wrong statement because of it.

No review needed here: this code was migrated into shikos-iced-liquid-glass and
reviewed there as PR #1. The commits land as they are — no rebase, no squash, no
rewritten messages. glass-pr1 stays as history.

The SPDX identifier in this repository is still the invalid bare form; that is fixed
in a separate task, against the merged tree.

feat: texture backdrop with procedural fallback 4691cf6e1f

Load assets/backdrop.png at pipeline startup (image crate, png-only
features) into an Rgba8UnormSrgb texture with a linear clamp-to-edge
sampler; every backdrop lookup — base, the three dispersion channels,
blur taps and the low-frequency milk layer — goes through one dispatcher
that samples the texture cover-fit for the widget aspect. A missing or
undecodable file logs a warn and falls back to the procedural test scene
(1x1 white placeholder keeps the bind group layout uniform). Uniform
block grows to 64 bytes (backdrop_mode + cover-fit scale), layout test
updated. Preview raised to 640x400 with the window sized to fit.

fix: backdrop moire and overbaked milk veil 420edbb739

Moire came from minifying the full-size texture without mipmaps: the
backdrop is now downscaled on the CPU at load (larger side to 1280 px,
~2x the preview, Triangle filter) so bilinear sampling stays alias-free;
no mip chain, per the calibration note. MATERIAL_TINT alpha drops
0.8 -> 0.4 (effective veil 0.32) so content reads through the glass on
bright backdrops; adapting the tint to backdrop luminance stays a
section-2 item. Verified that tint, soft layer and blur apply strictly
inside the shape: outside the AA band the fragment returns the plain
sharp backdrop sample.

The CPU now builds the full mip chain of the backdrop (successive x0.5
Triangle downscales to 1x1, one write_texture per level) and every
backdrop read is a single trilinear textureSampleLevel: refraction and
dispersion at lod = log2(1 + blur/2), the milk layer and luma probes at
maxLod - 2 — one mechanism replaces the spiral blur taps, the IGN
rotation and the 9-tap low-pass comb, and stays smooth over the whole
blur range. Regular milk is adaptive per Apple behavior: five probes
under the shape average the backdrop luma, k = smoothstep(0.35, 0.65)
picks veil color (dark glass on dark content) and opacity (0.55 -> 0.34,
thinner on light content); vibrancy chroma lift is x1.2. New
glass::Variant { Regular, Clear, Identity } cycled by a panel button:
Clear is a fixed 0.10 veil plus a bottom-dark scrim, Identity returns
the bare backdrop as the reference. Window sized to the 1000x700
preview. Procedural fallback keeps working; blur is inert there (the
scene has no mip pyramid).
