Summary by cubic

Upgrade dev dependency tailwind_merge from 1.5.2 to 1.5.4 in /gem to improve Tailwind class-merge correctness and small parse performance.

• Behavior change: axis shorthands now override logical sides; shadow-inner is grouped with shadow utilities. This may alter merged class output in dev/test usage.
• Stability/perf: parser reduces allocations; defaults are deep-frozen to prevent global-state mutation.
• Transitive: bumps sin_lru_redux 2.5.2 → 2.5.3. Scope is dev-only; only Gemfile.lock changed.
