- Translate the remaining 1,868 strings in a neutral infinitive style (no Sie/du), with German compounds, decimal commas and CLDR one/other plurals. - Review the #908 entries: knots are kn everywhere, the avionics codes BRG, CRS and DEST stay English like HDG and SPD, expand/collapse is ausklappen/einklappen, the radio toggle reads EIN/AUS, density SPARSE is DÜNN, the Thermal style is Wärmebild, German quotes in the shot prompt. - Register de: catalog, LOCALES, LOCALE_NAMES (Deutsch), package boundaries, same-as-english (codes, product names, music genres, units). - Tests: picker order and keyboard model with Deutsch, de/de-AT/de_CH normalization, browser de-DE resolves to German. - docs/translations/de.md: style, plurals, units and glossary; TRANSLATORS.md and CURRENT-STATE.md list German.
