/* ==========================================================================
   EmojiVista — main stylesheet
   Design: quiet warm neutrals + one sunny "emoji yellow" accent, rounded
   corners, soft shadows, generous spacing. System font stack (zero webfont
   requests = faster first paint). Dark mode via [data-theme="dark"] with
   prefers-color-scheme respected before JS runs.
