/* Company Reformation 2026 design layer (brief G6 / UX1-UX2).
   Calm, precise, Apple-grade: generous whitespace, one primary action per surface, soft depth,
   restrained NIIT navy / red / gold. Every colour comes from a token so light and dark themes are
   both first-class. Loaded after styles.css; refines the authenticated shell and styles every new
   Reformation workspace (prefix rf-). */
