…m improvements - Batch class collection and deduplicate before single addUtilities call (N compiler.build → 1) - Cache parsed CSS AST in setup-tailwind with clone-on-read to avoid redundant parsing - Walk rule.prelude instead of entire rule in extractRulesPerClass with early exit for non-matching rules - Add LRU eviction (max 50) to useSuspensedPromise to prevent unbounded memory growth

Summary by cubic
Optimized the Tailwind rendering pipeline to remove redundant builds and CSS parsing, and added an LRU cache for suspended promises to reduce memory on long-running servers. No public API changes.
Written for commit d843955. Summary will update on new commits.
