[Sync to prerelease] Add Typst path for blog-post skill thumbnails (#2019)
* skill(blog-post): add Typst path for thumbnails Existing blog-post skill only documented the HTML+SVG+screenshot path, which is heavy when the thumbnail is text-only or features a programmatic diagram. The 2026-05-05-quarto-2-parsing post showed Typst+cetz works well for diagram-driven thumbnails but the source assets weren't bundled, so the workflow lived only in one author's local checkout. This commit bundles the Typst path with everything contributors need: the page-setup template (text-only and diagram variants), a cetz node/edge scaffold matching the parsing post's graph helpers, and the white-on-blue Quarto wordmark SVG. The decision between Typst and HTML+SVG is surfaced as an explicit question in step 7 of the skill workflow rather than letting Claude silently pick. Release posts default to the existing HTML+SVG flow so the established release-thumbnail visual identity stays consistent. * fix(blog): bundle logo SVG with 2026-05-05 parsing thumbnail thumbnail.typ for the parsing post references quarto-logo-trademark-light.svg co-located in its directory, but the SVG was never committed — only existed on the original author's local checkout. Renders failed on a fresh checkout. Add the white-fill wordmark SVG (same one bundled in the blog-post skill assets dir) so quarto typst compile works for any contributor. Self-contained post, matches the convention of co-locating thumbnail.png with index.qmd. * skill(blog-post): bundle dark wordmark for light-bg thumbnails Symmetric to the white-fill variant for dark backgrounds. Authors adapting a template to the light palette (#F0F5F9) need the dark-text wordmark to keep the brand mark legible. Both files derive from the same brand-kit source and differ only in fill colors. typst-thumbnail.md gets a small table calling out which variant matches which background.

Two production paths exist for thumbnails. Pick before you start designing.

| Path | Use when | Avoid when |

|------|----------|------------|
11+
| **Typst** ([`typst-thumbnail.md`](typst-thumbnail.md)) | Text-only thumbnails, programmatic diagrams (trees, graphs, flow), version/title cards | Design uses 3rd-party logos/icons with their own colors |
12+
| **HTML+SVG** (rest of this guide) | Icon compositions with 3rd-party SVGs, photographic content, complex CSS-only layouts | Pure text or programmatic diagrams (Typst is faster) |
13+
14+
> **Release posts default to HTML+SVG.** The release thumbnail template (steel
15+
> blue + Quarto logo + version + small thematic emoji) is established convention

> from 1.4 through current. Switching to Typst for a release is a stylistic
17+
> choice — confirm with the team before deviating. New release posts that match
18+
> the template should reuse the existing HTML+SVG flow so all release thumbnails
19+
