/* Author `display: flex` below otherwise beats the browser's built-in
   `[hidden] { display: none }` UA rule regardless of specificity/order
   (author-normal always wins over user-agent-normal in the cascade), so

   silently do nothing without this override — the banner would render
   permanently and never dismiss on Accept/Decline, nor stay hidden for a
   returning visitor who already chose. Higher specificity than

  /* Same flex-basis-becomes-height bug as the email input fix below, in
     a different element: `.cookie-banner__text`'s `flex: 1 1 240px` is a
     *width* hint for the row layout above 480px, but `.cookie-banner`
     switches to `flex-direction: column` here, so 240px is read as a
     *height* on the now-vertical main axis. This was already live in
     production and pre-dates this fix pass, but was masked: the
     ~220px-tall broken email input (fixed below) pushed the submit
     button off-screen, so the banner's own oversized text block
     (measured ~240px tall) never visibly collided with it. Fixing the
     email input alone would have newly exposed this — a ~312px-tall
     banner covering the email field *and* submit button on phone
     viewports — as a regression against the test report's explicitly
     passed "banner does not vertically overlap submit button" check.
     Reset flex-basis so the text sizes by content instead. */

  /* Bug fix (post-/test): in the row layout above 480px, `flex: 1 1 220px`
     on the email input uses 220px as a *width* hint on the horizontal main
     axis. Once the column layout above switches the main axis to vertical,
     the same flex-basis is read as a *height* instead, producing a
     ~220px-tall broken-looking input on every phone-width viewport. Reset
     flex-basis to auto and let the input size itself by content/padding
     (a normal single-line field) at these widths; width is already 100%
     via `align-items: stretch` on the column flex container. */
