Problem

A user asked for calendar weeks to start on Monday instead of Sunday. This is likely a locale/usability issue for non-US users, but the exact calendar surface needs confirmation.

Product/scoping questions

• Which calendar surface is affected: player event calendar, retailer admin calendar, Pulse, or another view?
• Should week start follow browser/account locale automatically, or be a user/account setting?
• Is Monday-first only needed for display, or also date-picker/week navigation behavior?

Success criteria

• [ ] The affected calendar surface can display weeks starting Monday for users/locales that expect Monday-first calendars.
• [ ] The default behavior is clearly defined for US vs non-US users.
• [ ] Date navigation and event grouping remain correct across week boundaries.
