/* Tiny Butterfly — identity: soft and quiet, after oem.care. No outlines and no shadows: controls
   are pale grey pills, things sit centred on huge, almost-squircle white cards on off-white, type is
   a light neutral grotesk (Geist), and the mark is a little butterfly made of dots. The colours keep
   a faint airbrushed volume so they're the only thing with weight on the page. Light by default, like
   OEM; the dotted half-moon button in the header switches to dark (html[data-theme="dark"]). */
