📝 Walkthrough

Walkthrough

This PR updates Spanish locale files (i18n/locales and lunaria/files) adding and expanding translation keys across es, es-419 and es-ES variants. Changes introduce file-diff and compare UI strings, trends analytics copy (including copy_alt blocks), version distribution/grouping labels, size_increase and deprecation messaging, copy_version/copy_as_markdown, missing_permission messages, and about.sponsors / about.oss_partners entries. SEO/home description and tagline strings were adjusted. Multiple new public keys were added to support these UI features.

⚠️ Potential issue | 🟡 Minor

Plural agreement is off in compare.no_files_filtered output.

Line 1093 renders No hay archivos {filter}, but Line 1094-1097 provide singular forms (añadido, eliminado, modificado), which reads awkwardly in UI.

Suggested fix

     "filter": {
-      "added": "añadido",
-      "removed": "eliminado",
-      "modified": "modificado"
+      "added": "añadidos",
+      "removed": "eliminados",
+      "modified": "modificados"
     },

📝 Committable suggestion

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
