/* storytimeguru.com marketing home — page-local layout layer.
   shared/tokens.css is the source of truth for every brand value: the warm-editorial
   palette (paper / alt-band / card / ink / gold / Deep Blue / Vibrant Purple), the
   three type tiers (Montserrat display, Fraunces editorial, Open Sans body), the 8pt
   spacing + rhythm variables, radius, shadow, and the .section / .band--* / .card /
   .chip / .phone / .btn recipes. Nothing brand-y is hardcoded here, and this file
   introduces NO color, radius, shadow, or font of its own.

   Page-local additions (layout-only, deliberately not brand values):
