The build script now extracts content.json into derived data and copies
it into the app bundle, so no generated file is referenced from the
project or written into the repository. Signing is explicit: ad hoc for
the simulator, automatic with your own team for a device.

Android moves to Material 3 (navigation bar, app bars, list items,
bottom sheets, pager) with a real back stack. iOS hides the tab bar in
exercises so the bottom action is reachable, aligns content, and uses
system colours so themes and dark mode work. Both pick a readable
accent tint. Desktop keeps the VLSM table inside the window and gives
statistics the same header rhythm as other pages.
