Struct StylingHealth 

pub struct StylingHealth {
    pub formula_version: u32,
    pub score: f64,
    pub grade: &'static str,
    pub penalties: StylingHealthPenalties,
    pub confidence: StylingHealthConfidence,
    pub confidence_reason: Option<String>,
}

Project-level styling-health score: a SECOND health axis computed purely from the structural CSS analytics (CssAnalyticsReport), orthogonal to the JS/TS code-health HealthScore. Surfaced only alongside the --css analytics, so a plain fallow health run is byte-unchanged. The code score and grade stay untouched: styling health is additive, never folded into the code score.

Like HealthScore, the score starts at 100 and subtracts capped per-category penalties; the grade reuses the shared letter_grade thresholds verbatim (A>=85, B>=70, C>=55, D>=40, F<40), so the two axes are read on one scale.

Fields

formula_version: u32

Styling formula version; see STYLING_HEALTH_FORMULA_VERSION.

score: f64

Styling-health score in [0, 100]; higher is healthier.

grade: &'static str

Letter grade from the shared letter_grade thresholds.

penalties: StylingHealthPenalties

Per-category penalty breakdown.

confidence: StylingHealthConfidence

How much to trust the grade. Low in either of two cases, High otherwise (see confidence_reason for which): (1) the analyzed CSS surface is too thin for the declaration-normalized penalty rubric to be reliable (the gradeable, non-atomic declaration count is below 50); or (2) the project’s CSS is predominantly flat compile-time-atomic CSS-in-JS (StyleX/Panda), whose structure is not assessable, so the grade reflects token hygiene only regardless of declaration count. This is descriptive metadata that NEVER feeds the score: score/grade/penalties are byte-identical whether confidence is high or low. Gate on this confidence flag, which is the complete signal; do NOT reconstruct it from total_declarations, since that summary count includes atomic declarations the grade excludes (a large all-atomic project is Low despite a high total_declarations).

confidence_reason: Option<String>

Human-readable reason the grade is low-confidence: either the declaration and stylesheet counts a thin grade was computed from, or that structure is not assessable for compile-time-atomic CSS-in-JS. None when confidence is High. Prose, not a stable machine field: gate on confidence, not on this string.
