Chapter

A reader with notes — where typography, theming and text selection get tested for real.

Planned

Not built yet. Chapter is the typography and theming test: a whole screen made of text.

A library, a reading surface, and the notes that come out of it. Almost no chrome: what is left is type, spacing, color and one contextual toolbar.

Why this app

A reader exposes the tokens with nothing to hide behind:

  • Line height, measure and paragraph spacing come from the type scale, not from magic numbers.
  • Reading themes — light, sepia, dark, black — are color roles swapped underneath, with no component aware of it.
  • The app has to stay readable at the largest system font size without any layout breaking.
  • Text selection drives a dynamic toolbar instead of a system menu.

Screens

What it checks

  • The type scale holds a full page of prose, not just labels and buttons.
  • Adding a theme means adding colors, never touching a component.
  • Chrome that hides on scroll comes back reliably, including after a tap.
