Summary by cubic

Update dev dependency tailwind_merge to 1.5.3 in /gem to correct shadow class grouping and improve parsing performance. Previously shadow-inner was not grouped with shadow-*; it now is, which can change class merge outcomes. Defaults are now deep-frozen, blocking global config mutation.

• Review: check any class merging involving shadow-inner/shadow-* for expected results; ensure we do not mutate tailwind_merge defaults and pass custom config explicitly.
• Note: transitive bump to sin_lru_redux 2.5.3; no code changes expected.
