/* YogaVida main stylesheet (design system: docs/agents/design.md).
   Order: fonts, tokens, base, layout, components, header, footer, utilities.
   Only CSS logical properties (inline/block), so RTL (fa) and LTR (en) both work.
   Panel pages load this file too (then panel.css): keep the old token names and shared classes. */
