/*
  Baytak website. One stylesheet, one small script.
  Colour comes from the logo: the bowl of the "b" (#00847c) is the primary, the stem (#009898) its lighter partner.
  Neutrals are tinted with the same teal. Paid is the brand teal; Unpaid is the one warm ink (vermilion).
  Type is the app's own family, IBM Plex Sans Arabic, self-hosted. One corner system: 4 stamps, 8 buttons and plates, 12 panels.
