 * Palette: deep navy, warm white, a restrained teal. One accent only, so it keeps its meaning:
 * teal marks what you can act on (call, mail, register links) and the sworn credentials.
 * Layout uses logical properties (inline-start/end) throughout so the Persian page mirrors itself.
 * Every animation is switched off under prefers-reduced-motion.
