/* Get Asto Pro: goasto.com/pro/start/ (lib/astoapp/pro_start.py). goasto.com's own stage: black, Geist only, one
   accent (Asto teal), big statements, pill buttons; the site's font and brand files are its own (/assets/fonts,
   /brand). One question per screen, a four-part progress rail on top, nothing else competing for the eye. The
   signature: the rail fills in teal as you go, and each screen arrives with a short rise (still for reduced motion). */
