- Set Spanish as default language with ephemeral/encrypted privacy focus
- Translate all user-facing strings and legal pages to Spanish
- Replace Norwegian flag with Spanish flag in footer
- Remove Hemmelig/terces.cloud links, add cloudhost.es sponsorship
- Rewrite PrivacyPage: zero data collection, ephemeral design emphasis
- Rewrite TermsPage: Spanish law, RGPD, paste.es/CloudHost.es references
- Update PWA manifest, HTML meta tags, package.json branding
- Rename webhook headers to X-Paste-Event / X-Paste-Signature
- Update API docs title and contact to paste.es / cloudhost.es
