Zed resolves `injection.language` by matching it against the target
language's `name` field ( config.toml ) via UniCase, which folds case
but does NOT treat `-` as equivalent to ` `. The previous string
"pico-8-lua" therefore did not resolve to any registered language and
the entire __lua__ section rendered with zero highlights inside Zed.
Per `LanguageRegistry::language_for_name_or_extension` in
crates/language/src/language_registry.rs, only the `name` field and
`path_suffixes` are consulted — the directory under languages/, the
grammar `name`, the `scope`, and the tree-sitter.json `injection-regex`
field are all ignored. ( `injection-regex` is a Helix/Neovim
convention; Zed's production code never reads it. )
