A project whose root file is a .typ file now compiles straight to PDF with
Typst, as a third engine beside Quarto (.qmd) and latexmk (.tex). Dispatch
stays purely extension-based.
CLSI:
- New TypstRunner.js: runs `quarto typst compile <main>.typ output.pdf` (reuses
the Typst bundled in Quarto, so no extra binary / Docker change). stderr is
merged into output.log.
- CompileManager: _isTypstFile + a TypstRunner branch in _getRunner, and
TypstRunner added to the isRunning check and stopCompile kill list.
- RequestParser: 'typst' added to VALID_COMPILERS.
web:
- settings.defaults: 'typ' added to validRootDocExtensions and the text
extensions (so .typ opens in the editor); 'typst' added to safeCompilers.
- output-files: the Quarto/Typst log parser (which already understands Typst
`error:`/`warning:` + `┌─ file:line:col` diagnostics) now also handles .typ
compiles, so their errors/warnings populate the log tabs.
Polish:
- New-project menu: "Blank Typst project" + "Example Typst project" in both the
main and welcome dropdowns, backed by createBasicProject/createExampleProject
flavour 'typst', a new mainbasic.typ template and an example-project-typst
presentation (math, an image, a table, lists).
- Compiler dropdown gains a "Typst" option (cosmetic; dispatch is by extension).
README updated: three compilers side by side, with a Writing-a-Typst-document
section.

Quarto compiles (.qmd/.md/.Rmd, dispatched to QuartoRunner) write
Typst/Pandoc/Quarto diagnostics to output.log that the LaTeX log parser
does not understand, so the Errors/Warnings tabs stayed empty. Add a
dedicated quarto-log-parser that recognises Typst `error:`/`warning:`
(+ `┌─ file:line:col`), Pandoc `[WARNING]`/`[ERROR]`, Quarto CLI/Deno
`ERROR:`/`WARNING:`, and knitr `Quitting from lines`. handleLogFiles now
routes to it when the root file is a Quarto file (mirrors CLSI dispatch),
otherwise the LaTeX path is unchanged.
Also decouple the UI accent from the green ramp. The framework already
funnels every primary/accent surface (primary buttons, Bootstrap
$primary/$success, --btn-primary-background) through the --bg-accent-*
tokens; those just happened to point at Overleaf green. Introduce a
single $accent knob in foundations/colors.scss (with auto-derived
hover/tint shades) and repoint the accent tokens at it, defaulting to
the Verso/Quarto blue. Re-skinning the whole UI is now a one-line edit.

clsi-nginx.conf: the types{} block was overriding all nginx defaults,
leaving HTML/CSS/JS/fonts as application/octet-stream. Add the full
set of web MIME types so RevealJS assets are served correctly. Also
needed for X-Content-Type-Options: nosniff to pass.
CompileController.js: success was hardcoded to require output.pdf.
Also accept output.html so a RevealJS compile is reported as
'success' rather than 'failure'.
QuartoRunner.js: remove hardcoded --to typst --output output.pdf.
Instead run `quarto render` without --to/--output so the YAML
frontmatter decides the format (typst → PDF, revealjs → HTML, etc.).
Pass --embed-resources so HTML output is self-contained (flag is
silently ignored by the typst backend). After render, rename
main.pdf → output.pdf or main.html → output.html so the pipeline
finds the standard canonical filename.
output-files.ts: handleOutputFiles now falls back to output.html when
output.pdf is absent. Download URL uses outputFile.path instead of
the hardcoded 'output.pdf' string.
pdf-viewer.tsx: when pdfUrl contains output.html, bypass PDF.js
entirely and render a sandboxed iframe (allow-scripts for RevealJS
interactivity, allow-presentation for fullscreen).
Usage: set `format: revealjs` in the .qmd YAML frontmatter to get
an HTML presentation preview; set `format: typst` for PDF.

* Set scale synchronously on pagesinit to prevent 1.333 DPI flash
PDF.js resets its internal scale to 1.0 when setDocument() is called,
causing pages to momentarily render at the default 96/72 DPI scale
(1.333) before the React restore effect can apply the correct value.
Setting currentScaleValue directly in the pagesinit handler eliminates
this one-frame wrong-scale flash.
* Override .page display to block to prevent horizontal jump on recompile
Overleaf's global .loading class sets display:inline-flex, which
collides with PDF.js's transient 'loading' class on .page elements.
When the loading class is applied, inline-flex breaks margin:auto
centering, causing the page to jump horizontally. Forcing display:block
at higher specificity prevents the global rule from taking effect.
* Fix scrollToPosition offset using marginTop instead of borderWidth
scrollPageIntoView aligns the page content edge with the container top,
leaving scrollTop equal to the page's top margin (12px) rather than 0.
The previous correction used borderWidth (effectively 0) so the margin
offset was never compensated. Using marginTop scrolls back the correct
amount so the margin above the first page is visible.
* Prevent PDF viewer collapsing during recompile by preserving height
When setDocument() is called with a new PDF, _resetView() synchronously
clears all page elements, briefly collapsing the .pdfViewer div to the
viewport height. This produces a visible flicker before pagesinit fires
and pages are re-added.
Fix: record the current height and pin it as min-height on the .pdfViewer
element before calling setDocument(). A one-shot pagesinit listener
removes the constraint once the new pages are initialised at the correct
scale, by which point the element is already at its correct final height.
* Suppress PDF.js page-level loading spinner in Overleaf viewer
The PDF.js loadingIcon/loading classes briefly add a ::after pseudo-element
with display:block and contain:strict to each page div. Overleaf has its
own loading state UI so the spinner is redundant, and its activation was
the root cause of the shifts 4-5 height oscillation (the display change
broke CSS margin collapse on .pdfViewer, adding 2x page margins to its
computed height).
The display:block rule already added to .page prevents the direct cause
(Overleaf's .loading{display:inline-flex} colliding with the PDF.js class).
This rule makes the intent explicit by zeroing the ::after entirely.

* [web] Update paywall copy for plans-2026 AI tiers
Replace AI-related strings in upgrade/paywall UI when the
plans-2026-phase-1 flag is enabled:
- Add `higher_ai_allowance` ("Higher AI allowance") for paywall bullet
lists and body text; keep `higher_ai_limits` ("Higher AI limits") for
the subscriptions dashboard, which uses different wording per spec
- Update three locale strings to use "allowance" instead of "limits":
`access_all_premium_features_ai`, `plus_additional_collaborators_and_more`,
`upgrade_to_add_more_collaborators_and_more`
- Fix casing: `upgrade_to_review` "Upgrade to Review" → "Upgrade to review"
- Switch upgrade-benefits and onboarding prompt from `higher_ai_limits`
to `higher_ai_allowance`
- Fix subscriptions free-plan to show `higher_ai_limits` instead of
`get_unlimited_ai` under the plans2026 flag
- Fix compile-timeout button to show "Start free trial" under plans2026
instead of "Start a free trial"
- Update two Cypress assertions for the new track-changes modal title
* Update extracted translations for higher AI allowance
* Remove "start a free trial" with exclamation
* Remove "get unlimited ai" translation entries

The req.body.rootResourcePath has been shipped three weeks ago, so it's
unlikely to trip up stale editor sessions.
For now, only block node-fetch and log the rest.
