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.

12/// The icon set, re-exported so the paths read the same either way
13/// (`ui::icons::system::MAGNIFER`). It is a crate of its own because it is
14/// declared from an upstream set rather than drawn, and is useful to anyone
15/// painting gpui, component library or not.

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

67///
68/// Your own fonts go through this same gpui API — `add_fonts` takes any bytes,
69/// and [`theme::Theme::font_sans`] / [`theme::Theme::font_mono`] name which
70/// family the components then paint with.
