Struct AppBarStyle 

pub struct AppBarStyle {
    pub title_align: TitleAlign,
    pub show_traffic_lights: bool,
    pub height: f32,
    pub elevation: f32,
}

Per-widget platform styling for AppBar (D105 Phase 23 Step 3 — the proof-of-concept widget for the whole per-widget-Style-struct model). Per-instance builder calls on the widget itself (.height(..), .traffic_lights()) override these theme defaults; a widget that doesn’t set them falls back to whatever the active theme says.

Fields

title_align: TitleAlign

show_traffic_lights: bool

Draw faux macOS traffic-light dots. Stays false on every built-in theme, including macOS — a real window already has real OS traffic lights; this is decorative mockup chrome for docs/screenshots only (see the widget’s own doc comment), never something a theme should silently turn on for real apps.

height: f32

elevation: f32

Values above 0.0 draw the bar’s separating edge (today’s flat bottom border); 0.0 omits it. Not yet a real elevation/shadow effect — a coarser “on/off” proxy for the proof, real elevation rendering is later work.
