Changed condition from lang === 'de' to lang === 'en' so that all
non-English language subdirectories (fr, es, pt-BR, ru, de) correctly
resolve version.json via ../version.json instead of only German.

HowTo schema was hardcoded English — now uses {{HOWTO_*}}
placeholders. All 3 rich-result schemas are now locale-aware:
- FAQPage (expandable SERP snippets)
- HowTo (step-by-step SERP snippets)
- SoftwareApplication (entity understanding)
SoftwareApplication and Organization use language-neutral
brand name — no locale keys needed.
- lastmod bumped to 2026-06-01 for all 6 language roots
- xhtml:link hreflang entries added per URL (Google-recommended
belt-and-suspenders approach alongside HTML hreflang tags)
- FAQPage schema now uses {{FAQ_Q1}}..{{FAQ_A6}} placeholders
instead of hardcoded English — each language gets its own
schema for locale-matched Google Rich Snippets
- Q6 updated across all 6 languages: 'What if I don't trust
the official server?' + self-hosting Docker mention
PageSpeed Insights flagged AVIF files as uncached because the
@static matcher only included *.webp. Adding *.avif enables
1-year Cache-Control for all AVIF assets.
Google does not support sameAs for app store links in SoftwareApplication
rich results. sameAs is for identity pages only (Wikipedia, Wikidata, GitHub).
Store pages are independently indexed by Google and need no schema linking.
Google treats SoftwareApplication.sameAs as app listing references
(not social profiles like Organization.sameAs). This connects
KoalaSync's entity graph to both browser stores without
duplication risk.
