/* Attera — About page
   Hallmark · genre: modern-minimal · design-system: design.md

   Layout language: hanging label (S2 archetype).
   Each section uses a 2-column grid:
     LEFT column = small monospace label, top-aligned
     RIGHT column = content (heading + body)

   Bios get a richer LEFT: portrait + index + meta-list. */
