   Plane discipline (v2.4 §10.1 / §10.4): page CHROME (header/footer + logo) is
   BRAND palette (petrol); CONTENT is PRODUCT palette (felt table + walnut
   tabletop panels + rendered cards) because the page depicts gameplay. The
   logo never sits on felt. Body text targets WCAG AAA (≥7:1) for the 45+
   reader — textOnPanel #2B2118 on walnut #D5BE96 ≈ 9:1.
