/* ==========================================================================
   Merrell Leadership Group: base stylesheet
   Design direction: calm, editorial, never-hype. Feel of Simon Sinek /
   Patrick Lencioni / The Table Group: generous whitespace, quiet
   confidence, serif headlines over clean sans body copy.
   Colors are PLACEHOLDERS until final brand guide arrives: swap the
   values in :root when ready.
