Html

Html module: HTML escaping, safe HTML helpers, and template composition.

Provides utilities for escaping HTML entities, marking strings as safe (pre-escaped) HTML, rendering lists of items into IOLists, and composing template partials and layouts.

IOList is the canonical "rendered HTML fragment" type throughout this module. Fragments can be stored in Vault for fragment caching and re-embedded into parent templates via ~H sigils without double-escaping.
