/* 
 * Design cues aligned with readability & attention research:
 * — Lexend: typeface tuned for reading comfort on screens
 * — ~7:1+ contrast on body text (WCAG AAA where possible)
 * — Cool deep background: lower visual noise, supports sustained focus
 * — Single warm CTA (amber): salient without alarm-associated reds
 * — Teal accents: calm, associated with clarity in many UX palettes
