   PLAN YOUR MOUNTAIN DAYS — the ski landing's booking tabs.

   The words on the left change with the tab. On the right, a row of six icon
   tabs with hairlines between them — the one in use filled navy — and under
   it the short form for that tab: square-shouldered fields, navy selects,
   steppers with their buttons in a navy block, and a gold button.

   Kohwan's own colours and type (the ski pages' --skl-* tokens, with plain
   fallbacks). Prefix .skbt- throughout.
