/* PlainMoney — brand stylesheet
   Formula shared with nutrisize.health / insurance-site: white-canvas-style layout,
   Inter type, pill kickers, 14px card radius, tinted-hairline cards, dark footer band.
   Palette is PlainMoney's OWN — pulled straight from the shipped app's "Paper & Ink"
   theme (ios/PlainMoney/Resources/Theme.swift, android Colors.kt) so the site previews
   what the app actually looks like: warm paper, not white; deep green; amber only for
   genuine caution. Not a copy of nutrisize's green or insurance's blue — same formula,
   this product's own colors. */
