- core/display.py: write_positions() persists Arrangement's drag-and-drop
layout into niri's config.kdl (one output { position x= y= } per output),
validated via `niri validate` on a temp copy with a .kdl.bak backup before
writing — same pattern as core/keybindings.py's rebind(). Previously the
page only ever called `niri msg output … position set`, which niri treats
as live-only and drops on the next login/reload.
- gui/pages/display.py: Arrangement's Apply now runs each output's `niri msg
output … position set` synchronously instead of queuing them all on the
single-shot ProcessRunner (which rejects a second run() while the first is
still async) — a 2-monitor apply previously moved only the first output
and silently dropped the rest. _dock_to_nearest keeps the free axis at the
dragged position (so a shorter display can sit vertically centered next to
a taller rotated one) rather than forcing corner alignment.
- core/panel.py, files/__init__.py: incidental fixes alongside the above.
- packaging/: signing-key generation script + build-user systemd setup for
the [tanin] AUR auto-rebuild pipeline; PKGBUILD bumped to pkgrel=5.
- src/taninux/browser/: new module for browser theme sync (Fuji accent).
