  Disables non-essential animation/transition for users who have requested
  reduced motion at the OS level. Tailwind's `motion-reduce:` variant covers
  a few components explicitly (e.g. UploadZone's progress bar and spinner);
  this global rule is the safety net for everything else that renders
  `animate-*`/`transition-*` utility classes without an explicit override.

  The class-specific rules below complement the universal wildcard by
  explicitly zeroing out the most-common Tailwind animation/transition
  utilities.  They are required by the CSS-source integrity tests in
  app/invest/reduced-motion-contrast.test.tsx (issue #689) and serve as
  reliable hooks for components that can't add `motion-reduce:` inline.

  invoice-detail-* classes target InvoiceDetailClient.jsx and FundActions.jsx
  specifically (issue #31) — they suppress the `transition-colors` buttons
  and the low-opacity background fills that are illegible under reduced
  motion preference.
