/* NutriFlux brand identity (brand book 016 — colour palette, 011 — print font).
 * The four palette colours are exact and must not be substituted:
 *   Nutri Vital Leaf Green #38903a (PMS 7739 C) — main
 *   Fresh Flux Green       #77ae2c (PMS 369 C)  — main
 *   Active Lime Green      #abcd07 (PMS 390 C)
 *   Nutri Deep Root        #051d05 (PMS 3435 C)
 * Nunito is the only brand typeface: Black (900) for H1/H2, SemiBold (600)
 * for H3/H4, ExtraLight/Regular for body.
 * Tints and surfaces below are derived from those four, not new brand colours.
