Set conceallevel=2 and concealcursor=nc on .wiki buffers and add contained `conceal` matches for the bold/italic/code delimiters and wikilink brackets/targets. The static-fallback rendering now mirrors what the Neovim semantic-token path produced: *bold* shows as bold without the asterisks, [[target|desc]] shows just "desc", etc. The wikilink region uses an inline `contains=` (no line continuation) because some Vim builds (notably Homebrew Vim 9.2) raise E10 on the leading `\\ contains=...` form even though the surrounding region parses fine.

" syntax/vimwiki.vim — default highlight groups for nuwiki.

"
|
|
" Two responsibilities:
|
|
" 1. Default `@vimwiki*` highlight groups for the LSP semantic tokens
|
|
" (SPEC §11 P7). Loaded eagerly so the very first hover/highlight
|
|
" cycle after server startup already has colours.
|
|
" 2. A small regex-based fallback so static highlighting works on
|
|
" buffers where the LSP isn't running yet.
|
|
"
|
|
" The `@group.modifier` group names are Neovim's Tree-sitter convention
|
|
" — plain Vim rejects `@` and `.` with W18, so the LSP-token defaults
|
|
" are gated behind `has('nvim')`. The static fallback below works
|
|
" everywhere.
