   Pen N16 (PASS de Sergio, 2026-09-11): un solo documento, un formulario
   centrado que NO se mueve, y un entorno que cambia de personalidad alrededor
   (inicio · coach · atleta) con crossfade + escala sutil. Tokens = los del
   tema Noryn (theme-instrumento.css: tinta, sage, Geist). Sin librerías.
   Sin marca de workspace (PR24 / F3.28.5): aquí solo existe Noryn.
   ⚠ Estas páginas no llevan autoridad: son piel sobre Supabase Auth.
