/* ==========================================================================
   Stepling, stepling.app
   A landing page for a calm iPhone step counter.

   Design notes, so a future edit doesn't undo a decision by accident:

   - The palette is the app's palette, copied from the app's
     `tailwind.config.js`. Teal is the accent and it is used sparingly; duck
     yellow is celebration and mascot only, never data. Keep it that way and
     the site and the app read as one product.
   - "Pond" sections (`.band--pond`) are dark teal in both themes. That teal is
     the ground the mascot is drawn on. The duckling is near-white, so it
     disappears on anything lighter. See the app icon.
   - Light and dark are both first-class, because the app makes that claim.
   - Two typefaces: Fraunces for display (soft serif, a little wonky, the
     warmth the mascot promises) and Instrument Sans for everything else.
