/* =====================================================================
Bilitchi 2.0 — «اپرا — لوکس کلاسیک» component layer
1) theme-neutral new components (.o-*) — read tokens only, so they also work under Classic
2) Opera re-skin of the 1.x components ([data-theme="opera"] …) — the layer that makes every
existing page look Opera without touching its view
Load order on every page: tokens.css → app.css → opera.css → area CSS (@push('head')).
