   வாசி · Vaasi — pranayama practice, an Oliyon Research tool (vaasi.oliyonresearch.com)
   Two themes (NK, 3 November 2026): day = the Oliyon paper look, night = the dawn sky with a brass lamp.
   html[data-mode="light"|"dark"] is set by assets/js/boot.js before the first paint (auto = by the clock).
   The navy header bar, flame badge and footer are the same in both, as in every Oliyon Research tool.
   Text sizes are Thoothu's (oliyonresearch docs/SHARED-SPEC.md §4 "Text sizes").
   Layout: one centred practice column (max 580px) under the shared header; a session takes the whole screen.
