/* =================================================================
   Daily — Train for Life
   Design system: warm + playful, rounded, unhurried.
   Palette: committed olive, warmed neutrals, apricot/amber accent.
   Type: Fredoka (rounded display + numerals) · Hanken Grotesk (body).
   Motion tuned to Emil Kowalski's craft bar — strong custom easings,
   GPU-only transforms, press feedback, reduced-motion honored.
