M0.14: web bundle size — fat LTO, size-optimized glue, precompressed output
web profile: fat LTO, 1 codegen unit, strip, panic=abort, opt-level "s", with the per-pixel
crates (pipeline, raster, color, develop, geom, raw, codecs, scenes, preview, JPEG/PNG codecs)
kept at opt-level 3: "s"/"z" there cost +50 %/+130 % render time.
wasm 15.74 MB → 13.53 MB; brotli 3.47 MB → 3.09 MB (gzip 5.25 → 4.58 MB); worker slider job
3.8 → 4.0 ms (noise).
cargo xtask web writes .gz (-9) and .br (-11) copies next to each bundle file (pure Rust:
flate2, brotli) and prints a size table; --serve negotiates Accept-Encoding and serves them
with Content-Encoding. Measurements in docs/web.md → Bundle size.
