/* Design option C: Mindset. Dark and editorial, from his line "change isn't just physical,
   it's a mindset": deep teal-black (#0B2A33, the shadows of his own photos) with a light teal
   (#5FD0E3) for the words in italics, Instrument Serif for headings and Instrument Sans for
   reading. Buttons use the deeper teal (#006E82) so white words on them read easily. */
