/**
 * CSS/SCSS language adapter using tree-sitter-css WASM parser.
 *
 * CSS and SCSS files have no functions, classes, imports, or exports —
 * those methods return empty arrays. The adapter exists to enable AST-based
 * style declaration extraction for the style intelligence system (Spec 10).
 *
 * SCSS files are parsed with the CSS grammar. SCSS is a superset of CSS;
 * SCSS-specific constructs ($variables, @mixin, @include, @each, @for, @if)
 * will appear as parse errors but basic CSS declarations within rule sets
 * parse correctly.
