Foundations 0.5.2

This update makes the learning content primary throughout the app: smaller exercise cards, quieter navigation, and one compact answer toolbar with pen settings available on demand.

Typing now has a distinct answer field and muted preview, a searchable symbol picker that inserts only the selected command, and improved keyboard positioning. Expanded typing and handwriting share consistent navigation. Finger sketching uses the handwriting workspace, and photos attach directly after camera confirmation.

Reference views, figures, settings, and phone layouts have also been refined. Existing answers and handwriting are preserved. Typing tutorials remain hidden by default.
