/*
 * Apple design language layer for BibleAI — see docs/design/apple-design-language.md.
 *
 * Lives in BibleAI.UI so both hosts get one source of truth
 * (_content/BibleAI.UI/css/apple.css). Typography sits here rather than in
 * MudTheme because the brief asks for 72-96px headings that must still fit a
 * phone: clamp() expresses that, a fixed C# font size cannot.
 *
 * Light/dark needs no second rule set — every colour below derives from the
 * MudBlazor palette variables, which MudThemeProvider flips on theme change.
 * Translucency comes from color-mix() over those same variables, so the glass
 * surfaces follow the theme instead of hard-coding white and black.
