+LinuxFiles (the Files app running natively on Linux) (Uno Platform, Skia, X11). The screenshots are taken headlessly from a sandboxed
 home directory with synthetic drives (random labels, made-up sizes), so they never show the real machine's files, drives or user name.
 
-Last updated: commit `4b3cf79e6`, 2026-10-05 (see `showcase/captured.txt` for the exact shot list).
+The shots use the public "Win11" icon theme, selected the way the app does on a real desktop (kdeglobals `[Icons] Theme=`, GTK settings) inside the sandbox. The theme is copied into the sandbox only and is not part of this repository. Folder icons in the file lists render blank with this theme; the Home and sidebar icons come from it.

+Run `scripts/linux/showcase.sh` (add `--no-build` to reuse the existing build; set `SHOWCASE_ICON_THEME=Win11` to render with an installed icon theme, copied read-only into the sandbox). It uses `scripts/linux/headless-run.sh`,
 so nothing touches the real display, and rewrites `docs/linux-port/showcase/`. The synthetic drives come from `scripts/linux/showcase-drives.txt`.
 Set `SHOWCASE_SKIP="name name"` to record a regressed shot as "not yet working".
