/* ============================================================
   Hamed Khademi Khaledi — Arcane Library resume
   A warm, candlelit ancient library atmosphere kept as the
   identity: deep walnut walls, a soft arcane glow from runes
   and a candle flame, drifting dust motes. Sections are shown
   openly on the page (no book/scroll reading mechanic).
   Pure CSS + vanilla JS. No build step, no external calls
   beyond the Google Fonts stylesheet.
