Module theme_style 

Syntax → theme-element style bridge.

Maps a crate::style::Style syntax category to its builtin syntax.* / diagnostic.* [lattice_theme::ElementId], and resolves that to a concrete visual [lattice_theme::Style] via the active theme’s resolved table. The single source of the syntax→element mapping, shared by the cell builder, both renderers’ display-line paths, and the diff overlay.

Home (DX.2, BC.6 diff extraction). This lived in lattice-host (ui::theme) while the only consumers were host-side. It moves here so lattice-diff (the diff overlay) can reach it without the host. It belongs in lattice-syntax rather than the lattice-theme leaf because the bridge is inherently syntax-aware — it takes a lattice_syntax::Style — so the dependency points DOWN from this higher crate onto the theme leaf, keeping lattice-theme a minimal renderer-hot-path leaf (it deps only arc-swap + tracing). Host keeps a façade re-export (lattice_host::ui::theme::resolve_syntax_style) so existing call sites are unchanged.

Functions

resolve_syntax_style

Resolve a syntax category to its concrete [lattice_theme::Style] via the resolved table. The replacement for the deleted Theme::syntax_style color match — colors now flow from the active theme’s palette through the resolved table. Every syntax consumer (cell builder, display-line paths, diff overlay) calls this, then adapts the host Style to its renderer-native form.

syntax_element_id

Map a Style syntax category to its builtin syntax.* [ElementId]. The single source of the syntax→element mapping, shared by the cell builder, both renderers’ display-line paths, and the diff overlay.
