   Ypsi Sound Check — site stylesheet
   A night-gig look: deep ink-blue stage, signal-yellow highlights,
   poster-weight headlines. One dark theme, used on every page.

   How to use
   1. Add the fonts in your page <head>:
      <link rel="stylesheet" href="https://fonts.googleapis.com/css2?family=Bowlby+One&family=Atkinson+Hyperlegible:ital,wght@0,400;0,700;1,400&family=DM+Mono:wght@400;500&display=swap">
   2. Add this file after it:
      <link rel="stylesheet" href="ypsi-sound-check.css">
   3. Plain HTML (headings, links, paragraphs, tables) is styled automatically.
      Use the .ysc-* classes below for buttons, cards, labels and so on.
