/* DISPUTE Credit School: the public site. Paper, ink and a teacher's red pen. The red pen is the idea: a dispute is a
   correction, so the site marks up a credit report the way a teacher marks a test. Colors are the DISPUTE brand (rose,
   navy, gold) moved onto warm paper. Lexend for reading, OpenDyslexic one tap away, no all-caps and no italics in text. */
