" Standalone .flash files: use the Flash-exact regex syntax (syntax/flash.vim),
" not the Zig treesitter parser. The zig parser mis-parses Flash-specific syntax
" (`use X link Y` imports, `:=`) — ~0.5 ERROR nodes per line on real Flash code,
" and those regions render uncolored. The regex syntax has zero parse errors and
" colors every Flash construct correctly.
"
" The tutorial's ```flash markdown fences keep using treesitter-zig — that is a
" separate injection path (language registered in the user's config) and is not
" touched here; this only governs buffers whose filetype is `flash`.
"
" Deferred via vim.schedule so it runs AFTER any FileType handler that auto-starts
" a treesitter highlighter (NvChad), then stops it for this buffer and switches on
" the regex syntax. Removing the ftplugin symlink fully reverts to treesitter-zig.
