}

Stylesheet-level structural CSS analytics, computed from the parsed CSS syntax tree. Feeds fallow health penalty weights and located findings, never a standalone CSS score.

Fields

total_declarations: u32

Total declarations across every style rule (normal plus !important).

important_declarations: u32

Total !important declarations across every style rule.

rule_count: u32

Number of style rules.

empty_rule_count: u32

Number of style rules with no declarations.

max_nesting_depth: u8

Deepest style-rule nesting depth observed (0 = no nesting).

notable_rules: Vec<CssRuleMetric>

Rules that crossed the structural floor, in source order. Bounded; see Self::notable_truncated. The scalar aggregates above always reflect the full stylesheet regardless of truncation.

notable_truncated: bool

true when more rules crossed the structural floor than notable_rules retains (compiled utility CSS can emit thousands of !important rules), so consumers can note that per-rule findings were capped.

colors: Vec<String>

Distinct color VALUES in the stylesheet, sorted (a palette-size / design-token-sprawl signal). The parser canonicalizes notation, so the authored format is NOT preserved: red, #f00, #ff0000, and rgb(255,0,0) all collapse to one entry, and every legacy sRGB notation renders as hex. Notation-MIXING (hex vs rgb vs hsl) is therefore not detectable from this set; it would need a separate raw-token pass.

font_sizes: Vec<String>

Distinct font-size declaration values in the stylesheet, sorted.

z_indexes: Vec<String>

Distinct z-index declaration values in the stylesheet, sorted.

box_shadows: Vec<String>

Distinct box-shadow declaration values in the stylesheet, sorted. A high count signals an uncontrolled shadow scale (design-token sprawl).

border_radii: Vec<String>

Distinct border-radius declaration values in the stylesheet, sorted.

line_heights: Vec<String>

Distinct line-height declaration values in the stylesheet, sorted.

raw_style_values: Vec<CssRawStyleValue>

Bounded located raw styling values that bypass custom properties or token helpers. These are conservative declaration-level candidates for audit introduced-vs-base gating.

custom_property_definitions: Vec<CssCustomPropertyDefinition>

Located custom-property definitions with values. Internal staging consumed by the health layer for nearest-token suggestions.

defined_custom_properties: Vec<String>

Distinct custom properties (--x) DEFINED in the stylesheet, sorted.

referenced_custom_properties: Vec<String>

Distinct custom properties REFERENCED via var() in the stylesheet.

defined_keyframes: Vec<String>

Distinct @keyframes names DEFINED in the stylesheet, sorted.

referenced_keyframes: Vec<String>

Distinct @keyframes names REFERENCED via animation / animation-name.

registered_custom_properties: Vec<String>

Distinct custom properties REGISTERED via an @property rule, sorted.

declared_layers: Vec<String>

Distinct cascade layers DECLARED (via @layer a, b; statements or named @layer a { } blocks), sorted.

populated_layers: Vec<String>

Distinct cascade layers POPULATED by a named @layer a { } block, sorted. A layer declared but never populated (and not imported into) is a cleanup candidate.

defined_font_faces: Vec<String>

Distinct font families DECLARED by an @font-face rule in the stylesheet, sorted. A declared family referenced by no font-family anywhere is a dead web-font payload (cleanup candidate).

referenced_font_families: Vec<String>

Distinct font families REFERENCED via font-family / font in the stylesheet, sorted (generic keywords like serif excluded).

declaration_blocks: Vec<CssDeclarationBlock>

Per-rule declaration-block fingerprints for rules at or above the minimum block size, used to detect duplicate declaration blocks across the project. Internal staging consumed by the health layer; never serialized (the public output is the grouped duplicate_declaration_blocks).
