/*
 * BT Kitchen Tools — brand styles for Butter & Thyme.
 * Sage #A3B899 and deep thyme #4F6B45 (from the logo mark), butter
 * accent #F0C75E, cream card #FBF7EE, warm brown ink #40342A.
 * Headings: "Fraunces" (Georgia fallback). Body: "Nunito Sans"
 * (system fallback). The two font stacks live in the variables below
 * so they can be pointed at the theme's fonts in one line.
 * Mobile-first: most visitors arrive from Facebook on a phone.
 * Sizing is container-relative only — no viewport units for tool elements.
