# Lib Layout

This app now uses a prototype-friendly vertical-slice structure.

Use `lib/app/` for bootstrap, shell navigation, shared app-state wiring, and
local persistence. Use `lib/features/<slice>/` for product work inside a
single slice. Use `lib/core/` only for cross-cutting primitives that are not
owned by one feature.

If you are starting work, open the slice README first. Most old top-level
files are now compatibility exports that point to the new canonical location.
