 * Trainer palette — the web app's colors, not the mobile app's.

 * The action colors are literally the ones the solver's strategy grid uses
 * ([solver/strategy-grid.tsx]) so an action reads the same whether you meet it
 * in a solve, an Explorer range, or a drill. Everything else (table felt, seats,
 * chrome) comes from the zinc/token palette in globals.css, so the trainer sits
 * inside the app instead of importing the mobile app's navy + teal.
