- Impressum rewritten with real Austrian business data (ECG instead of
German TMG references); UID, Gewerbeberechtigung and Firmenbuchnummer
marked as pending until available
- Real contact email/phone/address across footer and Impressum
- Meta description, Open Graph tags and favicon on all pages
- Gallery images now offer both 800w and 1920w srcset candidates
- Lightbox traps focus while open and restores it on close
- Header/footer extracted into partials/, pages now built from
templates/ via `npm run build` (scripts/build.js) to remove
duplication across the 4 pages
node_modules was accidentally committed alongside sharp's native
binaries. Added .gitignore and .gitattributes (enforce LF) so this
doesn't happen again.
