/* tasteskill / base.css
   A neutral foundation: reset, token names, fluid type steps, a 12-column grid, states and the motion
   helpers from references/motion.md. It has no look of its own. Copy it into the project, replace the
   token values with the ones on the direction sheet, and build on top. Delete what you do not use. */
