/* ---- hidden attribute must actually hide ----------------------------------
   FIX 2026-08-20. `.scan-form { display: flex }` is an author rule and so beats
   the UA stylesheet's `[hidden] { display: none }`. Consequence: account.html
   set emailForm.hidden / codeForm.hidden on a successful sign-in and NOTHING
   HAPPENED — the sign-in panel stayed on screen with the readings rendered
   underneath it. That is very likely the second half of what Stephen reported
   as "opens all prior searches below": the form never went away.
   Same trap applies to showStage2(), the intake page's #pair-fields, and any
   future element toggled with the hidden attribute. One global rule, so the
   next person to use `hidden` on a flex element does not rediscover this. */
