/* =========================================================================
   Pio — asistentul Profesio (buton plutitor dreapta-jos + panou).
   Aspect 1 la 1 cu prototipul v4 (base/static/proto/v4/index.html: sectiunea
   „Pio" din GACSS + constanta PFX). Aceleasi reguli exista si in
   base/static/css/profesio.css; aici sunt duplicate IDENTIC, in aceeasi ordine,
   cu prefixul .ga-pf, ca asistentul sa arate la fel si pe shell-urile vechi
   (front/instructor/student), unde profesio.css nu se incarca.
   Tokenii de culoare sunt definiti pe .ga-pf (aceleasi valori ca in
   profesio.css), cu varianta intunecata pentru data-theme (layout-ul nou),
   data-bs-theme (shell-urile vechi) si prefers-color-scheme.
