   Drop-in stylesheet that adds the v0.2 thesis additions to the

     · Motion tokens    (--motion-prana, --motion-kantha, --ease-jala)
     · Rasa tones       (--tone-shanta, --tone-vira, --tone-karuna, …)
     · Prahara hooks    (--prahara-tint, --prahara-name)  — set by prahara.js
     · Jaali surfaces   (--surface-jaali, --surface-jaali-soft)
     · Brahmasthāna     (.layout-brahmasthana — 9×9 / 5×5 grid utility)
     · Empty states     (.empty-state composition primitives)
