/* ERP2.0 Connect public landing page (landing page plan).
   SACC teal and charcoal on warm paper, a serif for reading and a system sans for labels; no web fonts and nothing from
   elsewhere. The layouts change from section to section on purpose, and only three things move: the sample invoice
   printing itself, the getting-started timeline, and the tier slider. All motion stops when the visitor's system asks
   for reduced motion. */
