Multi-Language Capability Guide

multi_language is a product-level capability layered on top of the shared localization infrastructure.

What it enables

When enabled, Tov+ allows:

• multiple active locale variants per occasion
• actor language preference to influence guest-facing locale resolution
• planner access to localized occasion and event authoring
• planner access to actor language-preference editing
• guest rendering that prefers localized content when it exists

What still works without it

Without multi_language, Tov+ still has localization infrastructure, but product behavior stays in single-default-locale mode:

• the occasion default locale still exists
• guest experiences still render safely in the default locale
• planner and guest flows still work without localization errors
• advanced multilingual authoring and actor preference controls stay unavailable

Relation to localization infrastructure

The shared localization capability continues to provide:

• locale normalization
• locale fallback helpers
• localized content storage seams

The multi_language capability decides whether the product is allowed to use those mechanics for richer multilingual behavior.

Occasion and actor behavior

• enabled: occasion localized content, event localized content, and actor language preference are all active inputs to rendering
• disabled: occasion default locale wins, actor preference is ignored, and localized authoring is hidden

Planner and guest behavior

• planner settings show the localization workspace only when multi_language is enabled
• guest experiences resolve locale using actor preference only when multi_language is enabled
• guest experiences fall back cleanly to the occasion default locale when the capability is absent

Fallback behavior

Fallback remains deterministic:

• capability enabled: requested locale -> actor preference -> occasion default -> system default
• capability disabled: occasion default -> system default
