📝 docs: the server integration page reads in Spanish, French and German
Keeps 'UseInitialThemeMode' as its own heading, so the anchors other pages aim
at it resolve unchanged, and repoints the hreflang ones, whose slug the
translated heading moves.
The French heading drops its space before the colon: removing the colon leaves
two spaces, which GitHub turns into two hyphens, and an anchor nobody can
predict is an anchor nobody can link to.
✨ feat: the wiki reads in five languages
Spanish, French and German join English and Portuguese: 25 of the 39 pages
translated, each language with its own `_Sidebar.md` under `locale/<culture>/`,
which is the file GitHub resolves beside a page and the site reads as that
language's navigation.
The language switch on every page lists only the languages whose file EXISTS,
so a page with no Spanish yet offers the four that are there and never a dead
link. It is generated rather than written, so each tranche of translations
lights its own entries and nothing has to be remembered.
Version marks carry over verbatim: the `eq:since` comment is byte-identical
across languages and only the italic word changes (Since / Desde / Depuis /
Seit). Production reads the comment and never the word, so the runtime is
language-agnostic; the one place that knew the words was the site's own guard.
Still to translate, the fourteen longest: BuildFlow, Capabilities, CodeEditor,
Compiler, Debug, DesignSystem, Diagnostics, Icons, Photon, ServerEvents,
ServerIntegration, SupportedFeatures, Upgrading, VisualEditor.
Also drops 150 em-dashes from the English pages and 134 from the Portuguese
ones, on the pages this commit touches.
