 * HRD-Mobile — Auth Presentation Styling (M01 PART 01E)

 * Scope: every selector below is namespaced under `.auth-*`, so this file adds
 * nothing to and changes nothing in the M00 shell. It defines no second design
 * system: all colour, spacing, radius, typography, elevation, motion, and
 * touch-target values come from styles/tokens.css.
