/* ============================================================
   MyTaxSVB lane sites — shared stylesheet
   Mobile-first. One 42rem reading column. Lane accent via --accent:
     efinready.com  #1E6B4E   (deep season green)
     yourflow.tax   #0E5A8A   (working blue)
     buildmysvb.com #7A3E12   (earned bronze)
   Each lane page overrides --accent in a tiny inline <style>.
   Voice of the visuals: warm paper, ink, one strong accent —
   a well-thumbed planner, not a corporate deck.
