Greptile Summary

This PR localizes the sponsor directory and sponsor purchase surfaces, including page titles, calls to action, purchase-result messages, tier empty states, and monthly pricing labels.

• Adds ten sponsor-related keys consistently across all locale catalogs.
• Adds the corresponding keys to the generated language type contract.
• Replaces hardcoded sponsor UI text with values from the active language catalog.
• Fixes the previously reported untranslated sponsor-directory page shell.

Confidence Score: 5/5

The PR appears safe to merge; no actionable correctness, security, or repository-rule violations remain.

The locale catalogs and generated type contract are aligned, all changed sponsor-page lookups resolve, and the previously reported hardcoded page-shell title has been fully localized. The HTML-rendered thank-you value is supplied only by trusted bundled catalogs, so the examined injection path is not reachable.

Important Files Changed

Filename	Overview
src/pages/sponsors/sponsors.js	Replaces directory text and the page-shell title with catalog values while preserving tier grouping and sponsor loading behavior.
src/pages/sponsor/sponsor.js	Localizes purchase-page headings, pricing units, and completion or error messages without changing the purchase flow.
src/lang/index.d.ts	Extends the localized-string type contract with all newly consumed sponsor keys.
src/lang/en-us.json	Defines the English source values for the complete set of sponsor localization keys.
src/lang/id-id.json	Supplies Indonesian translations for all sponsor-page strings.
src/lang/ar-ye.json	Retains permitted English fallback values while keeping its key set aligned with the source catalog; the same pattern applies to the other untranslated catalogs.
