Open-Now Hours Widget

Build an "Open now" opening-hours widget for my business as ONE self-contained snippet (HTML + <style> + <script>, every class prefixed "oh-").

- Business: [Your business name]
- My hours: [Your opening hours]
- Holidays / special days: [e.g. 25 Dec closed, 1 Jan 10 AM – 2 PM]

REQUIREMENTS
- Keep the hours in one easy-to-edit JavaScript config: 24-hour times, an array of ranges per day so a day can have split shifts (e.g. 08:00–13:30 and 16:00–22:00), [] for closed days, plus a HOLIDAYS map keyed by YYYY-MM-DD
- Always calculate with India time (Asia/Kolkata via Intl.DateTimeFormat), whatever the visitor's device time zone
- A status badge: green "Open now" with "Open until X PM today", amber "Closing soon" in the last 60 minutes, and red "Closed now" with the next opening ("Opens tomorrow at 9 AM" or "Opens Monday at 9 AM")
- A card with the badge, today's line, a holiday note when relevant, a Monday-to-Sunday table that highlights today, and two buttons: "Get directions" (Google Maps link) and "Call"
- A compact badge version for my site header that uses the same logic
- Refresh the status every minute; accessible markup; mobile friendly

Return the snippet in one code block and explain how to edit the hours.
