/* AdLedger website: the "Quiet Ledger" look of the app (docs/redesign/BRIEF.md §2).
   Sage-graphite neutrals, one emerald accent that means money, ink primary buttons.
   Radius rule: 8px for controls and chips, 14px for panels, full for tags.
   Colours always come from the tokens below (never hard-coded greens), so the page follows
   light and dark mode and a future accent change in one place. */
