- The catalog-completeness test requires a non-empty Czech label for
every key of the reference (Japanese) table.
- Czech context keys: `Page Layout|Orientation` and `Orientation` get
different labels; unknown text such as `Sheet1!A1` passes through.
- `cs-CZ` / `cs_CZ.UTF-8` system tags and `parse("cs")` resolve to Czech.
- The ribbon renders after switching to Czech, and the choice persists
in UiState.
- Czech keeps canonical formula entry (`=SUM(1.5,2.25)`), and `=SUMA(1;2)`
is not accepted.
- The UI font draws every Czech accented letter, upper and lower case,
without tofu; Czech shares the default Han font order.
Czech spells "Data" as English does, so the Czech checks probe
"Formulas" -> "Vzorce", where an English fallback would be caught.

Language::Es was registered and switches formulas to Spanish (SUMA, decimal comma, semicolon
arguments), but every interface label still fell back to English. This adds es.rs with all 266
labels in Excel's Spanish wording (Combinar y centrar, Inmovilizar paneles, Análisis de
hipótesis, Buscar objetivo, Rastrear precedentes…) and covers Spanish in the i18n tests.
