LineCommentContent { ![\n]* } matches the empty string, which Lezer
rejects as a zero-length token (infinite-loop risk). Change to ![\n]+
and mark it optional in the LineComment rule so empty // comments parse.

Any item shared between headingTitleItem and document-level item causes
a shift/reduce conflict: the LALR automaton merges the two contexts and
makes the shared token ambiguous. The only structural fix is to make
HeadingTitle a terminal (external tokenizer) that reads greedily to EOL,
giving the LR state machine a context-isolated token that can never
collide with document-level item tokens.
Removes headingTitleItem sub-rule, HeadingText token, and updates
styleTags to match HeadingTitle directly.

Removing Strong and Emphasis from headingTitleItem eliminates the
conflict: both appear in document-level item, causing the LR automaton
to merge heading-title states with document-item states and make "*"
ambiguous (Strong opener vs. end of heading).
HeadingText is widened to ![\n$#`<@\\]+ so "*" and "_" inside headings
are consumed as plain text rather than producing error nodes.

headingTitleItem* allowed an empty HeadingTitle, causing a shift/reduce
conflict: after HeadingMark, seeing "*" the LR parser couldn't decide
whether to shift it as a Strong inside the heading or reduce HeadingTitle
to empty and treat "*" as a document-level item.
Changing to headingTitleItem+ forces HeadingTitle to be non-empty, so
"*" after HeadingMark must be inside the heading. Empty headings are
handled by Lezer's error recovery.

Strong{strongItem{Emphasis}} and Emphasis{emphItem{Strong}} created a
mutual-recursion cycle that caused Lezer's LR automaton builder to
produce exponentially many states and crash.
Remove each construct from the other's item list. StrongText already
includes '_' and EmphText already includes '*', so nested delimiters
render as plain text inside the opposite construct rather than errors.

Replace the StreamLanguage tokenizer with a full LR grammar compiled by
@lezer/generator, giving Typst the same parse-tree infrastructure that
LaTeX and BibTeX already use.
Grammar features:
- Headings (=, ==, …) via SOL-detecting external tokenizer
- Code expressions (#keyword, #func(args), #ident.method, #{…}, #[…])
- Named argument highlighting (key: value in function calls)
- Inline and display math ($…$)
- Strong (*…*) and emphasis (_…_) with bold/italic formatting
- Raw blocks (```lang…```) and inline raw (`…`)
- Nested block comments (/* /* */ */) via depth-tracking external tokenizer
- Labels (<name>) and references (@name)
- Backslash escapes
Infrastructure changes:
- lezer-typst/typst.grammar — new Lezer grammar
- lezer-typst/tokens.mjs — external tokenizers for context-sensitive lexing
- scripts/lezer-latex/generate.mjs — Typst added to grammars array so the
existing lezer-latex:generate script (and Dockerfile step) compile it
- .gitignore — generated typst.mjs / typst.terms.mjs excluded from git

Replace the custom regex-based ViewPlugin with the official
@codemirror/lang-yaml package. yamlFrontmatter({ content: mdLS })
wraps the Markdown language with a mixed parser: the leading ---/---
block is handed to the full Lezer YAML parser (proper key/value/scalar/
anchor/alias highlighting), while the document body continues to use
the Markdown parser. The manual Frontmatter extension import is also
removed since yamlFrontmatter handles frontmatter recognition itself.

Typst: heading tokenizer now colors the entire heading line (not just the
'=' prefix), and bold/italic markers (*/_) map to strong/emphasis tags
rather than the generic operator tag. A typstHighlightStyle applies
bold/italic formatting even when the active theme lacks .tok-heading.
Quarto: enable @lezer/markdown's Frontmatter extension so the YAML header
is no longer mis-parsed as Setext headings. A new ViewPlugin decorates
frontmatter lines with type-appropriate CSS classes: keys (tok-typeName),
string/bool/number values, comments, and the --- delimiter markers.

- Hide the Present button when the current output is a PDF (it only makes
sense for HTML/RevealJS decks).
- Publish now supports PDF projects: snapshot output.pdf and serve it inline
via a small index.html wrapper at /p/:token, so link holders can view the
PDF straight from the published version.
- Add a Typst document outline (scans '=' headings) wired into the file
outline panel.
- Dashboard branding: enlarge the instance-name/version text and let the
sidebar Verso wordmark span the full column width.

- Add a Typst language (stream highlighting + completions) for .typ, and
Quarto completions (code chunks, callouts, cross-refs) for .qmd/markdown.
- Project dashboard: new Format column (Quarto/Typst/LaTeX) from the cheap
project compiler field, surfaced through the projects list API.
- Compiler dropdown: grey out engines that don't match the root file's
extension (.qmd->Quarto, .typ->Typst, .tex->LaTeX engines).
- Replace the Overleaf fill loader with an animated Verso logo: the four
quadrant circles drift on their own orbits while colour warms up with load
progress; reused on the token-access screen too.

Two fixes to the Markdown/Quarto file outline:
1. The last frontmatter line (e.g. `format: typst`) appeared as a
heading. The Lezer Markdown grammar has no frontmatter support, so it
reads the closing `---` of the YAML block as a Setext underline and
promotes the line above it to a heading. Detect the leading
`---`...`---`/`...` block and skip any heading inside it.
2. Pandoc/Quarto attribute blocks were shown in titles, e.g.
`## Slide {.smaller auto-animate="true"}`. Strip a trailing `{...}`
from the extracted title.

The outline entries showed up at the right lines and jumped correctly,
but their titles were blank. The text-extraction walked the heading
node's children and collected non-HeaderMark child text — but in the
Lezer Markdown grammar a heading has NO child node for its text; the
only children are the HeaderMark nodes. The title text lives in the
gaps between marks, so the walk collected nothing.
Slice the whole heading's source instead and strip the markers:
leading/trailing '#'s for ATX headings and the '==='/'---' underline
for Setext headings.

outline.ts: export NestingLevel so it can be used outside the file.
markdown/document-outline.ts: new enterMarkdownNode function that walks
the Lezer Markdown syntax tree and extracts ATXHeading1-6 and
SetextHeading1-2 nodes, mapping them to the same NestingLevel enum
used by the LaTeX outline (Section→SubSection→SubSubSection…).
Wrapped in makeProjectionStateField for incremental updates.
markdown/index.ts: register markdownDocumentOutline as a CodeMirror
extension in the Markdown LanguageSupport so the StateField is active
whenever a .qmd file is open.
codemirror-outline.tsx: fall back to markdownDocumentOutline when the
LaTeX documentOutline StateField is not present in the editor state
(i.e. when the active language is Markdown, not LaTeX).
