/* Design tokens: presenting-your-voice. Turquoise, blue and white; calm, respectful, high contrast.
   Palette: white paper, deep blue (header/footer), light turquoise as a FILL/BORDER only, dark turquoise links.
   Contrast (hand-calculated, AA+): ink on white ~16:1, dark-turquoise link on white ~6.4:1,
   white on deep blue ~11:1, ink on light turquoise fill ~11:1, error-700 on white ~6.5:1, success-700 on success-bg ~6:1.
   Light turquoise is never used for text. Type: system stacks only, large base size, roomy line height.
   Names such as --color-navy-* are what the shared layout CSS reads: navy-800 is deep blue, navy-700 dark turquoise. */
