/* ==========================================================
   Design system
   - Quirky handwritten font (--display) is reserved for "chrome":
     the logo, the hero greeting, section dividers and hub-page
     titles, and button/badge labels.
   - Everything that is actual content — a case study's own title,
     a project card's name, sub-headings — is the plain sans
     (--body), just bigger and bolder. Titles are never mixed with
     paragraph text in the same font by accident.
   - Never pure white: text is a soft lavender off-white
   - One type scale, one spacing scale, used everywhere
   ========================================================== */
