// PERF: Prism used to import every bundled language (~574 KB lazy chunk). We now
// ship a curated subset covering the languages actually seen in chat. Imports
// MUST stay in dependency order (Prism component files assume their base grammar
// is already registered): base grammars (markup/css/clike/javascript) first,
// then languages that extend them (e.g. c→cpp, javascript→typescript,
// markup+javascript→jsx, jsx+typescript→tsx, markup→markdown).
