/* American Dream Reality Index — site styles.
 *
 * Palette matches the author's Substack visual identity so the two sites
 * read as a family:
 *   navy   #0b2d52  (primary type, wordmark, chart line)
 *   cream  #FBEFD9  (page background, card fills)
 *   amber  #d97706  (single accent: links, focus, chart annotations)
 *
 * Type: Playfair Display for the display wordmark and page headings,
 * Source Serif 4 for body copy. Both self-load from Google Fonts; the
 * font-family stacks fall back to system serifs so the page remains
 * readable if the fonts fail to load.
 *
 * No framework, no CDN beyond the font files.
