/* MyExamHub — design system
   Palette: Burgundy & Mint (pinned by client brief)
   --color-accent-strong is a derived, non-pinned addition: the mint accent
   (#4FD1B5) is too light to pass text/focus-ring contrast on the pale
   backgrounds, so light mode substitutes a deeper teal wherever accent is
   used as foreground rather than as a decorative fill/border. Dark mode's
   accent-strong is identical to accent since mint already contrasts well
   against the near-black surfaces there.
   Direction: growth-journey narrative, clean editorial execution

/* ===== Palette switcher: Burgundy & Sage =====
   Primary/Accent/Secondary don't change between light/dark (same pattern
   as the default Burgundy & Mint palette), so one block covers both
   themes; only --color-accent-strong needs a theme-specific value, same
   reasoning as the default palette's accent-strong.
   Note: this palette's Primary (#331623) is identical to the dark-mode
   --color-surface. Every place Primary is used as text/icon color already
   has a dark-mode override to accent or text (added for the Mint palette's
   own contrast fix), so nothing goes invisible — the one visible side
   effect is the tree-journey node's decorative border blending into its
   own fill in dark mode, which is cosmetic only. */
