Live opening status banner

The pill sits next to the menu and shows Open, Closing soon or Closed live, with the next opening time, even across a public holiday or a holiday break. Time is always Paris time, whatever the visitor's time zone. The eleven French national public holidays are computed every year (Easter, Ascension and Whit Monday included), with an Alsace-Moselle option; exceptional closures are declared with plain dates. One click opens the details: the week's hours with today marked, upcoming closures and a phone link. Accessibility: native details element usable from the keyboard, Escape closes it and returns focus, table with row headers and aria-current on today, AA contrast in light and dark modes, pulse disabled with prefers-reduced-motion. Without JavaScript the hours stay readable.
