/* ============================================================
   ליסטה — light-first, colorful theme + dark mode toggle.
   Default: bright, lively surfaces with a violet/teal color
   pairing. Optional dark mode: near-black canvas, translucent
   borders. Every rule below is written against CSS custom
   properties so both themes share one ruleset — only the
   [data-theme="..."] blocks differ. Theme is applied as
   data-theme="light"|"dark" on <html>, toggled via auth.js and
   persisted in localStorage. All class names kept 1:1 with the
   previous stylesheet — no functional HTML/JS changes needed.
   ============================================================ */

/* Fonts are loaded via <link rel="preconnect"> + <link rel="stylesheet">
   in each page's <head>, NOT via @import here. An @import inside the
   stylesheet serializes the download chain (HTML -> style.css -> parse ->
   discover @import -> fonts), blocking render twice; the <head> links let
   the browser start both requests in parallel immediately. */
