Webview-zoom-style presets: Extra small 0.8 / Small 0.9 / Default 1.0 /
Large 1.2 / Extra large 1.5, applied through SLINT_SCALE_FACTOR set at
the top of main() before any thread or the backend exists. The env var
overrides the compositor DPR, so the value is last observed DPR x
preset; the Default preset leaves the var unset (stock DPR handling,
including live monitor changes, stays intact). last_dpr is persisted
from the winit window (real compositor DPR) on the 5s renderer-sentinel
timer.
- const-bake guard: strip SLINT_SCALE_FACTOR in qbz-ui build.rs so the
slint compiler never bakes the factor into the generated code
- new UiScale global + scale-divided window minimums keep the physical
minimum constant across presets (XL fits a 1366x768 screen); the
three window-geometry gates in main.rs use the process-active factor
- artwork decode targets scale with the preset: sharp covers at >=1.2,
smaller decoded-cache footprint below 1.0
- Settings > Appearance "Interface size" row below Language (replaces
the commented-out percentage placeholder and its orphan properties),
restart-to-apply toast
- Typography.boost = 1.1 on Extra small only, so body text stays
readable at the 0.8 factor; Small (0.9) needs no compensation
- i18n: new strings added to all 7 locale catalogs
Known accepted limitation: slight text softness at fractional scale
factors (owner-accepted; diagnostic notes live in
qbz-nix-docs/ui-scale-presets/).

Slint cannot split the .slint compilation across crates, but a Slint LIBRARY
crate exposes its generated Rust types to dependent crates (verified with a
minimal proof). So:
- NEW crate `qbz-ui` (lib): owns the whole .slint tree + build.rs + bundled
translations; `slint::include_modules!()` + the generated types (AppWindow,
MiniPlayerWindow, all globals/structs) are re-exported. Translation domain is
now `qbz-ui` (the .po files renamed accordingly).
- `qbz-slint` (bin) -> renamed to `qbz` (package + `[[bin]] name = "qbz"`),
reclaiming the binary name from the retired Tauri app. It depends on `qbz-ui`
and does `pub use qbz_ui::*;` so existing `crate::AppWindow` / `crate::*State`
references resolve unchanged.
This splits the single ~20 GB rustc into two crates (UI/codegen vs the 75k LOC
of logic) — the foundation for lower build peak, incremental caching, and the
upcoming per-feature crate extraction.
Also fixed for the move: qbz-i18n bundled-.po include paths, the font/WGSL
`include_bytes!`/`include_str!` paths (-> ../../qbz-ui/ui/), workspace members,
dev scripts (`-p qbz`), and the CI workflows. `cargo check -p qbz` is green.
