/* BudTrader design tokens and base components.
   Single source: shared/bt-base.css. The build copies it into the theme and (from Phase 1B) the core plugin, and
   tools/parity.py fails if a copy differs.
   The greens come from the logo: "Bud" is #009349 and "Trader" is #22BE73. The logo is never recolored. White text on
   #009349 is 3.99:1, under the 4.5:1 that labels need, so light-mode actions use it deepened by 10% (#008442, 4.80:1) and
   links by 20% (#00763A, 5.25:1 even on the soft background). The bright green is used as it is in dark mode and on
   dark bands (7.5:1). Color carries meaning and is never swapped: green = BudTrader and actions, permit blue = license
   and compliance status, placard amber = paid placement and warnings. */
