pub fn logo() -> Option<PathBuf>Expand description
Path to the brand logo SVG for the currently active mode.
Convention: branding/{mode}/logo/logo.svg. The “main” logo —
usually the wordmark variant a shell would put in an “About”
dialog or a splash. Pair with logo_square / logo_horizontal
when the surface dictates a different aspect ratio.
Resolves through branding_asset with the same three-step
fallback (active mode → opposite mode → no-mode), so a theme that
only ships one mode still produces a usable path.
