/* The [hidden] attribute must always win.
   Without this, any element whose class sets display:grid/flex/inline-block
   (the drawer, the modal, the floating button, a hidden form field, a badge)
   ignores hidden="true" and stays on screen. One rule prevents a whole class
   of bugs — including invisible overlays swallowing clicks.
   Kept at the END of the file: a browser does not care, but test browsers with
   a simpler cascade resolve it the same way as real ones this way. */
