3D scene:
- Build a procedural world from seeded waypoint segments (per-segment
step/turn/altitude params) joined into kink-free Catmull-Rom curves,
using ghost points so boundaries stay smooth; world and textures are
derived from the session seed for consistency.
- Carve the flight corridor out of the terrain (gaussian dip plus a
height floor 32u below the path) and add city districts with instanced
buildings driven by seeded glowing-window textures, plus tunnel
segments rendered as textured tubes with light strips.
Board UI:
- Add a ViewSwitcher to the kanban header and a board view provider.
- Compact group cards place an inline "+" on the last visible to-do row
(shrink-0, so it sits at the row's right edge) that opens the new
TodoCreateDialog, alongside the existing AI-assisted creation flow.
Scheduled panel:
- Collapsed rail replaces the corner overdue dot with badges stacked
below the calendar icon: overdue (destructive, ping ring) and
due-today (neutral, calmer pulse). Today's count is a separate filter
that excludes already-completed occurrences, unlike the overdue count.
