/* Tanoo Mohal: portfolio
   Layout system adapted from dqnamo.com: a narrow column, section header
   (title + muted subtitle), a "tray" holding cards with concentric radii, and a
   "view all" row closing each tray. Greys follow the Radix gray scale; dark is
   the default, light is opt-in via the dock. */
