   MATTRESS-GUIDE.CSS
   Page-specific additions for mattress.html
   ──────────────────────────────────
   HOW TO USE:
   Load AFTER styles.css and comparison-table.css in <head>:

   <link rel="stylesheet" href="assets/css/styles.css">
   <link rel="stylesheet" href="assets/css/comparison-table.css">
   <link rel="stylesheet" href="assets/css/mattress-guide.css">

   Same pattern as male-style.css — only touches
   .post-container content. Header, footer, and
   sidebar are untouched. Uses only the existing
   --pink, --dark, --ink, --cream, --warm, --muted,
   --border, --white, --ease variables from styles.css.
