1//! ui — SwiftUI-flavored components for gpui. Reached as `bezel::ui`.
2//!
3//! Style flows through the environment, never through parameters: components
4//! read [`theme::Theme`] (a gpui `Global`) at paint time, the way
5//! SwiftUI views read `@Environment`. Motion comes from the named
6//! `motion` catalog.

35/// Bundled so the type ships with the binary instead of depending on what the
36/// host system happens to have installed.

41/// Static Geist weights alongside the variable file: gpui's cosmic-text path
42/// (Linux) rasterizes variable fonts at their default instance only — it never
43/// applies `wght` coordinates — so medium/semibold/bold text silently paints
44/// at 400 with just the variable TTF registered. The statics give the face
45/// matcher real 500/600/700 faces (macOS/CoreText applies the variable axis
46/// natively and simply never falls through to these).
47/// They cover the sans only — Geist Mono ships as the variable file alone, so
48/// the cosmic-text path paints every mono weight at 400.

56/// Register the bundled fonts with the gpui text system. Failure is non-fatal:
57/// the theme's system fallbacks take over (same families the CSS stack names).
58///
59/// Your own fonts go through this same gpui API — `add_fonts` takes any bytes,
60/// and [`theme::Theme::font_sans`] / [`theme::Theme::font_mono`] name which
61/// family the components then paint with.
