/* ══════════════════════════════════════════════════════════════
   menubar.css — the site header: green dot stickers on a clean white bar
   (the same green as the cursor). Left: the logo sticker → home.
   Right: ART · ABOUT · RESUME stickers. Each is flat matte paper at a slight
   tilt with a thin shadow, like a round sticky note; on hover it straightens
   and lifts as if you're about to peel it; the current page is pressed flat.

   Loaded LAST on every page, so it's the one place the header is styled.
   Selectors start with ":root body" so they outrank older per-page rules.
