Type Tour

A handful of phone-OS screens set entirely in two faces from the Expose type program, to feel them in context on a real phone: Exciting Lilt (the display face: Semibold and Bold, 17 px and up) for clocks, titles, marks, and the few alerts that deserve attention, and Exposure Sans Original 10 (the text face: Regular, Medium, Semibold, Bold, and an Italic) for everything else. Lilt's Bold sets titles and actions from 17 to 36 px, where it matches Sans Bold's colour. Its Semibold sets the clock, the widgets' large numerals and the 48 px-and-up sizes.

Nothing here is a real app. The screens are authored in app.contract, the taps move between them, and the data is the words on the screen. There is no data crate to speak of (data/ answers nothing) and no JavaScript.

• Lock screen — the clock in Lilt, four notifications. Tap the clock, the hint, or the Messages notifications to leave it.
• Home screen — two widgets, sixteen icons whose marks are Lilt, a dock. Messages, Settings, and Type Tour open; the rest stay put. Tap the time to lock the phone again.
• Settings — a Lilt large title over an Exposure Sans list, with working Airplane Mode and Bluetooth switches. Display & Text Size has a text-size chooser that scales Messages and the Settings list, and a specimen of both families side by side.
• Messages — six conversations, each openable, with a composer.

The home indicator at the bottom of every screen goes home.

The faces are copies of fonts/exciting-lilt/ExcitingLilt-{Semibold,Bold}.ttf (v10, 2026-09-29) and fonts/exposure-sans/original-10/*.ttf (0.010) from the Expose repository, MIT-licensed there; re-copy them into assets/ when a new build lands. Both families are declared in the Contract and bound to these bytes (LLP 1019 D3), so an installed font of the same name is never consulted.
