/* ============================================================
   WCAG AA ACCESSIBILITY SHADES
   Derived from the GDF Brand Guidelines (April 2026 audit).
   The brand primary #19b5ef has only 2.36:1 contrast against
   white, failing WCAG AA for both normal text (4.5:1) and
   large text (3:1). The shades below preserve the original
   hue (196-197 degrees) and saturation (85-87%), darkening
   only the lightness channel to meet AA thresholds.

   #0c7199  WCAG AA button/CTA background
            HSL(197, 85%, 32%) - brand hue, 20% darker
            White text on #0c7199: 5.47:1 (passes AA normal)
            Used for: btn--primary bg, btn--phone bg, sidebar
            card bg, footer bg, CTA banner bg

   #0b7199  WCAG AA text color (links, headings on light bg)
            HSL(197, 87%, 32%) - brand hue, 20% darker
            #0b7199 on white: 5.47:1 (passes AA normal)
            #0b7199 on #d0eefb: 4.51:1 (passes AA normal)
            Used for: --color-primary-text token, anchor color,
            prose links, related-card headings (light mode)

   #0a6585  WCAG AA hover state
            HSL(196, 86%, 28%) - brand hue, 24% darker
            White text on #0a6585: 6.54:1 (passes AA normal)
            Used for: btn--primary:hover, btn--phone:hover

   The full-value brand primary #19b5ef is preserved for all
   decorative and non-text uses: hero accent text on dark
   backgrounds, dark-mode links and buttons (where it achieves
   7.94:1 on #231f20), logo rendering, gradient accents, and
   glow/shadow effects.
