/* [hidden] must always win. The UA stylesheet's implicit [hidden]{display:none}
   is easily defeated by any component rule that sets display (eg. .stat-tile{
   display:flex}, .plate-grid{display:grid}), because those are author rules
   with equal or higher precedence. gates.js relies on the hidden attribute as
   a fail-closed compliance guarantee — an unverifiable claim must stay off
   screen even if JS never runs. This is a correctness guarantee, not a
   styling preference, so no component-level display rule may override it. */
