/* Latent RL Prior project page.
   One type scale and one content column are shared by every section:
   - type: --fs-xs labels, --fs-sm captions/notes, --fs-md dense text in cards and tables,
     --fs-base body, --fs-lead lead/question, --fs-h3, --fs-h2, --fs-num numbers, --fs-h1.
   - layout: every block aligns to the .container edge; no section is centered except the hero. */
