Per-field language tabs for spatie/laravel-translatable in Filament 5. Every locale is a real input in the form state at the same time, so translations survive Repeater, Builder, ->relationship() repeaters, settings pages and custom pages without a model. No global locale switcher that loses repeater data, validation runs for every language, plus table columns and infolist entries that show the current language with a fallback to the default and any filled one.

Per-file alt text (per locale), a decorative flag, caption, title and focal point for Filament 5's own FileUpload and SpatieMediaLibraryFileUpload — one wrapper around the upload you already have, no media library to adopt. A missing alt is reported (form badge, optional validation, data attribute) and never replaced by the file name; an accessible Blade component renders alt, caption and the focal point as object-position.
