Struct SyntaxContext 

pub struct SyntaxContext {
    pub lang: Lang,
    pub registry: Arc<LangRegistry>,
    pub resolved: Arc<ResolvedTheme>,
    pub ids: BuiltinElementIds,
}

D.3.b.2 (2026-05-29): the per-session syntax context the provider needs to populate Cell.fg with theme-resolved token colours.

The refresh task threads this through from DiffOverlayRefreshTask::spawn so the provider doesn’t have to plumb the host’s syntax / theme types into its public surface. None (passed as syntax: Option<&...> in DiffOverlayVirtualRowProvider::render_rows) means “don’t syntax-highlight” — useful for tests and for languages with no registered grammar.

Fields

lang: Lang

registry: Arc<LangRegistry>

resolved: Arc<ResolvedTheme>

T.5.b: the resolved theme table + builtin element ids the deletion-block highlighter resolves syntax colours through (replaces the old theme: Theme field — the only thing it was used for was Theme::syntax_style, now lattice_syntax::resolve_syntax_style).

ids: BuiltinElementIds
