/* Ker Craft - kercraft.com
   ---------------------------------------------------------------------------
   Direction: joyeux et rond. A tiny studio making tools that take an annoyance
   away, so the site should feel like a relief, not like a spec sheet.

   Big squircle icons, saturated tints, chunky sticker shadows, bouncy easing.
   Gabarito for the voice (geometric with a grin), Figtree for the reading.
   Sober here means little text and no clutter, not muted.
