/* Imagination Applied — visual system.
 *
 * Built from the Brand Guide section 10 (Visual Expression) and the actual
 * logo and joshpenzell.com design tokens.
 *
 *   Premise      "A rehearsal room for the future."
 *   Principles   Structured, then interrupted · Evidence of motion ·
 *                Human before futuristic · Editorial, not SaaS ·
 *                Playful with restraint.
 *
 * Palette is taken from the head-and-paper-airplane mark, and matches
 * joshpenzell.com (--primary navy, --secondary teal) so the two sites read as
 * one house. Guide colour direction: a quiet paper ground, strong dark ink,
 * ONE confident cool colour (navy, for systems and clarity), ONE warm accent
 * (orange, for motion and risk). Teal is the mark's signature. Magenta is
 * punctuation and is used about twice.
 *
 * The guide's Avoid list is binding here: no red curtains, no comedy/tragedy
 * masks, no glowing brains, no circuit patterns, no binary as texture.
