- Settings → Appearance: mode Dark / Light / System (follows the OS live) and
a named theme remembered per mode — dark: Default, Darcula, Apple Dark;
light: Default, Apple Light, IntelliJ Light, Canvas. Each theme is a
CSS-variable override block keyed by `data-theme` on <html>; the sidebar
quick toggle gains System and swaps between the two remembered themes.
- An inline boot script in index.html applies the stored mode and theme
before first paint, so a reload no longer flashes the default colours.
- Diff +/- rows are easier to tell apart on every theme: a /20 status tint,
a 3px status bar and a bold coloured marker; the changed-span emphasis no
longer vanishes on light themes.
- #42: the Add-lane modal (Repo mode / "Current branch") asks
POST /api/lanes/ensure with `exact: true`. Without it a folder nested inside
an existing lane resolved to that parent lane with created:false, so the
modal closed and no new card appeared. When the folder really already has a
lane, the modal now says which one instead of closing.
Closes#42
