A native-rendered task inbox written entirely with the experimental canvas.Ui declarative builder. The whole app is one elm-style loop — Model → Msg → update → view — with no hand-assigned widget ids, no absolute frames, and no string command dispatch:

Widget identity is structural (tree path + keys), so keyed rows keep their ids across rebuilds, reorders, and filtering.
Layout is flex (gap, padding, grow, alignment) resolved by the canvas engine.
Pointer and keyboard events resolve to typed Msg values through the tree's handler table (tree.msgForPointer / tree.msgForKeyboard).

Run it (macOS):

zig build run
