   ceol web — master stylesheet

   This file is intentionally thin. The styles are split into modules under
   modules/. The @import order below replays the modules in the exact same
   sequence the rules originally appeared in this file — CSS is order-sensitive
   (cascade + specificity ties depend on source order), so this order MUST be
   preserved. Do not reorder.

   @import statements must come first in a stylesheet, so nothing else lives
   above this block.
