   Accessibility-First CSS Improvements
   ======================================== */

/* 1. COLOR CONTRAST - WCAG AA Compliant */
:root {
  /* Color palette with good contrast ratios */
  --text-primary: #1a1a1a; /* High contrast for readability */
  --text-secondary: #333333;
  --text-light: #666666;
  --bg-primary: #ffffff;
  --bg-secondary: #f5f5f5;
  --border-color: #cccccc;
  --focus-color: #0066cc;
  --focus-outline: 2px solid var(--focus-color);
  --focus-offset: 2px;
}

/* 2. VISIBLE FOCUS INDICATORS */
:focus-visible,
button:focus-visible,
a:focus-visible,
input:focus-visible,
textarea:focus-visible,
select:focus-visible {
  outline: var(--focus-outline);
  outline-offset: var(--focus-offset);
  box-shadow: 0 0 0 3px rgba(0, 102, 204, 0.1);
}

/* 3. SKIP LINK - Allow keyboard navigation */
.skip-link {
  position: absolute;
  top: -40px;
  left: 0;
  background: var(--focus-color);
  color: white;
  padding: 8px;
  text-decoration: none;
  z-index: 100;
  border-radius: 0 0 4px 0;
}

.skip-link:focus {
  top: 0;
  outline: var(--focus-outline);
  outline-offset: var(--focus-offset);
}

/* 4. HEADING HIERARCHY
   Semantic hierarchy (correct h1→h6 nesting) is a markup concern, not a
   CSS one — enforcing it in CSS via blanket font-size/line-height/margin
   on every heading fights whatever the theme already defines for that
   specific heading (hero titles, card titles, section titles all have
   their own sizing). Removed the size/line-height/margin resets; kept
   only a sane minimum weight so headings are never accidentally as thin
   as body text. */
h1,
h2,
h3,
h4,
h5,
h6 {
  font-weight: 600;
}

/* 5. TEXT READABILITY
   Line-height/letter-spacing are visual-design decisions the theme
   already makes per element. Forcing them globally on `body` cascades
   into every heading/component that doesn't set its own line-height,
   which is what was making spacing feel loose site-wide. Kept only the
   16px minimum body font-size (a real mobile-accessibility/no-zoom
   requirement) and let the theme control rhythm otherwise. */
body {
  font-size: 16px; /* Don't go below 16px for accessibility */
}

p {
  max-width: 80ch; /* Optimal line length — doesn't affect spacing */
}

/* 6. LINK ACCESSIBILITY
   WCAG 1.4.1 requires links not be distinguished by color ALONE — but it
   explicitly doesn't require underlines on links that are already
   distinguishable another way (buttons, nav items, cards, badges with
   their own shape/background/icon). Forcing underline on every <a>
   fights the theme's own component styling (blog cards, CTA buttons,
   nav links) and was overriding it because :not([role="button"]) has
   higher specificity than the theme's plain `a` reset. Scoped to actual
   prose links instead — this matches the pattern style.css already uses
   for its own paragraph-link hover state. */
