Files Created/Modified

Created:

• plugins/golem15/translate/components/LocaleSuggestionBanner.php - Component with browser detection
• plugins/golem15/translate/components/localesuggestionbanner/default.htm - Banner partial
• themes/quotify/assets/css/components/locale-banner.css - Banner styles

Modified:

• themes/quotify/partials/account/update.htm - Added Language Preference section
• themes/quotify/layouts/default.htm - Registered and rendered banner component
• themes/quotify/assets/css/app.css - Imported locale-banner.css
• plugins/golem15/translate/Plugin.php - Registered LocaleSuggestionBanner component

Decisions Made

• Banner shows localized text in the suggested language (Polish/German) rather than current page language
• Uses 1-week dismissal cookie to prevent annoyance while still showing eventually
• Banner appears after flash messages, before page-wrapper for maximum visibility

Deviations from Plan

None - plan executed exactly as written.

Issues Encountered

None.

User Setup Required

None - no external service configuration required.

Next Phase Readiness

• Language preferences fully functional for logged-in users
• Browser language detection and suggestion banner working
• Ready for Phase 15-04 (Auto-redirect Strategy) if planned
