Struct RendererTextFontTraceSnapshot 

pub struct RendererTextFontTraceSnapshot {
    pub frame_id: FrameId,
    pub entries: Vec<RendererTextFontTraceEntry>,
}

Per-frame renderer-owned font selection trace, intended for diagnostics bundles.

This is not a stable contract for apps; it exists to make font fallback issues auditable and to help keep refactors fearless (especially around variable fonts and fallback chain semantics).

Fields

frame_id: FrameId

entries: Vec<RendererTextFontTraceEntry>

Bounded list of trace entries for the frame.

Renderers are expected to keep this list small. Typical policies:

• record entries only when missing/tofu glyphs are observed
• record a small ring of the most recent prepared blobs when explicitly enabled
