/*
 * Shared progress UI for Gallery / Annotate / Calibrate / Presentation / EXIF / Lab.
 * Lives under lab/static because the Lab server only serves this directory;
 * web pages load it via ./auto_iqa/lab/static/ (review.css @import).
 *
 * Markup: .ui-progress root (+ --inline | --overlay | --block), .ui-progress__track >
 * .ui-progress__fill, optional __label / __meta / __cancel. `is-indeterminate` goes on the root.
 * Colors are literal so every tool renders the same bar regardless of its own --accent.
