## Per-language data values (i18n for data-driven templates)

Data files (`data/**`) can now provide **language maps** — values whose keys are your configured language codes — and they resolve to the language of the page being rendered. This makes data-driven templates like the bundled **Trust Center** bilingual without duplicating data files.

### Language maps

Any data value may be a map keyed by language code:

```yaml
# data/trust/faq.yaml
- question:
    en: Where is data stored?
    de: Wo werden Daten gespeichert?
  answer:
    en: Data is stored in the EU.
    de: Daten werden in der EU gespeichert.
```

When the page renders for `de`, the value resolves to the German variant; for `en`, the English one. Resolution falls back to the default language, then to the first present entry, so a partially translated value still renders something sensible.

A map is only treated as a language map when **all** of its keys are configured language codes. A map like `{ icon: "shield", label: "Security" }` is left untouched, and plain strings, numbers, and booleans pass through byte-for-byte — existing single-language sites produce identical output.

### The `i18n` filter

Resolution is exposed as a Tera filter (alias `localize`) for use in any template:

```html
{{ value | i18n(lang=lang) }}
```

The bundled `trust-index.html` and `trust-item.html` templates already apply it to all prose fields — certification name/description/scope/auditor, subprocessor name/purpose/location, and FAQ question/answer — so the Trust Center is bilingual out of the box.

### Missing-translation warnings

When a value is present in some but not all configured languages, the build prints a warning that points at the path and the missing language(s), so gaps in translation are easy to spot:

```
⚠ Warning: data.trust.faq[0].answer: language map missing translation(s) for de
```
