Bands
paper --m-surface (#FAF9F5) The default band — warm paper. Most sections.
cream --m-cream (#EBEDE4) The alternate light band. Use between two paper sections to break the cadence.
ink --m-near-black (#25261D) or the dark variant via [data-marketing-dark] The emphasis band — a dark interruption between light sections. Pricing, big quote, hero closer.
cobaltrare --m-cobalt (#354CEF) Demoted, barely used. Jade is the brand colour — cobalt is a rare legacy data-accent, reached for almost never. At most one small moment per page, never two adjacent. When in doubt, use the ink band instead.
Rhythm rules
  • Alternate paper ↔ cream across consecutive light sections — never two identical backgrounds adjacent.
  • Drop an ink (dark) band between light sections for emphasis; it resets the eye and spotlights one idea.
  • A SlideFrame `background` variant (paper · cream · ink · cobalt) sets the band; the dark variant flips `--m-*` roles via `[data-marketing-dark]`.
  • Jade is the brand colour — it carries the accent across every light band. Cobalt is demoted and barely used; if you reach for it at all, it is one small moment per page, never adjacent to another saturated band.
  • Keep vertical rhythm consistent: bands share a section padding scale; only the background changes.
