/* ==========================================================================
   Impulse — product landing page (hosted at impressions.co/impulse)
   Light re-skin of the standalone Impulse marketing site into the
   Impressions in Ink brand: the EXACT process inks from tokens.css
   (Cyan #00ADEF / Magenta #ED008C / Yellow #FCBA00) + Source Sans 3, so
   /impulse harmonizes with impressions.co while keeping Impulse's own
   layout, dark/light toggle, and motion. tokens.css is loaded first and
   supplies --font-sans / --font-serif; the three inks are also pinned
   here so this sheet renders correctly even if load order shifts.
   CMYK ink identity · light default · dark = the infographic art
