/* Tactile controls: the workspace's control language, carried onto the site.
   Mirrors the platform's tactile-controls.css (Aperture Chat v0.5.14):
   - Recessed: tracks hold choices, wells hold a row of related actions.
   - Lit: the current choice and the main action are the teal key.
   - Raised: everyday buttons sit up and press in when clicked.
   - Grooves: a key that stands alone sits in a channel cut into the surface, the
     way the Drafts actions sit in their well.
   Loaded after the page styles so it restyles the shared controls. */
