/* Button reset lives in the main design-system stylesheet (loaded first, as this
   file's dependency). Duplicating it here isn't just redundant — since this
   stylesheet is enqueued site-wide (not only on event pages), it loads *after*
   component styles like .askbar__chip that share the same selector specificity,
   and the later-loaded duplicate reset was winning the tie and stripping their
   pill background/border sitewide. */
