/* Cornhole - the stylesheet.
   NOTE ON [hidden]: no rule in this file sets `display` on `.help` or on `.open`.  Any class rule
   that sets display would OVERRIDE the [hidden] attribute, and the symptom is an invisible panel
   that still swallows every click on the page.  The help panel is hidden by the attribute alone
   (via the [hidden] rule at the top) and `.open` only changes opacity and transform.
   tools-harness-page.js asserts this by parsing the file rather than trusting the comment. */
