/* ============================================================
   Encyclopedia Afghanica — css/style.css

   The ONLY stylesheet. All presentation lives here; HTML pages
   must never carry inline styles, <style> blocks, or scripts.

   Design language: classic scholarly — serif text on warm paper,
   a single reading column, hairline rules, quiet oxblood accents.
   Dark mode follows the OS automatically. RTL is pre-wired for
   the future ps/ and fa/ mirrors.

   Selectors are limited to elements/classes permitted by the
   canonical template in AGENTS.md §4.
