/*
 * Upstate Sound & Repair – Stylesheet
 *
 * This file defines the visual style for the one‑page site.  It
 * draws on mid‑century modern influences with a limited colour
 * palette, generous white space and geometric accents.  The
 * layout is responsive, collapsing the navigation into a hamburger
 * menu on small screens.  Colours are defined as CSS custom
 * properties so they can be easily tweaked in one place.
