/* Palette. This block is the single source of the console's colours; everything below uses the tokens.
   Precedence: :root is the Light theme; the media block gives the Dark values to Auto (no data-theme
   on <html>, the OS says dark) but not when data-theme="light" is set; :root[data-theme="dark"] forces
   Dark. The two dark blocks must stay identical, and must declare the same token names as Light (a Go
   test checks both). theme.js sets data-theme from the saved choice; without it, Auto follows the OS.
   Charts: series 1 is --accent, series 2 --series-alt (orange); the pair passes the colour-blind
   separation and 3:1 contrast checks on --card in both themes. */
