/*
  Keypool, drop look. Built around the Classic drop logo.
  Design language:
   1 mood     calm, clear water. One drop. Safe and simple.
   2 palette  abyss #06323d, sea #0b6173, shallows #e8f6f8, ink #0b3a4a, aqua #8de3ee, coral #ff9b85 (warnings only)
   3 type     Gabarito (display, UI) + Be Vietnam Pro (body); system mono for keys
   4 shape    big radii (24-32px), pill buttons, drop-shaped bits
   5 depth    frosted glass on the deep sea, white cards with soft shadow on the shallows
   6 motion   slow and water-like; one ease; ripples; everything stops under reduced motion
  Parts: Ripple, Ripple Button, Number Ticker (Magic UI), BlurText (React Bits), glass card + ring loader (Uiverse, G4b413l + mrhyddenn),
         toast (Opensource UI). All MIT (React Bits: MIT + Commons Clause).
