"Canon" was leaking onto the public site — a nav item, a footer block, a
page title, a set of CSS class names. It was also driving content
decisions it had no business driving: the backlog was ordered around
which references were still unused, which is curation dressed up as
planning.
The page is now /references/, the list is documented as a bibliography
to grow rather than a canon to curate, and the backlog says plainly that
a sin earns a slot by being worth a page — sources are found to support
it, never the reverse.
Adds six sources (Cairo's Truthful Art, Few's Show Me the Numbers, the
Economist's audit of its own charts, Kosara's eagereyes, WTF
Visualizations, Datawrapper's dual-axis piece) and roughly doubles the
citations on the five published sins, to 5-7 each. Two of the new notes
point at sources that complicate our own position rather than back it.
The Economist essay ships without a URL rather than a guessed one.

Link previews are the funnel for a "send the link" site, so give every sin
a share-optimized card.
- og/twitter meta tags on every page (poke as description, canonical URL,
summary_large_image)
- Per-sin 1200x630 card generated at build: the poke, the before/after
charts (uniform height so tall vconcat charts fit), severity meter,
category, and short citations — composed with satori, rasterized with
@resvg/resvg-js, no browser needed
- Default brand card for the homepage and canon
- Shared chart pipeline extracted to lib/renderChart.ts (used by both the
on-page component and the card generator)
- Bundle three IBM Plex TTF weights for the rasterizer

Make each sin a self-contained page you send instead of re-explaining:
- Per-sin "poke" one-liner (the shareable callout)
- Citations system: a canonical bibliography (src/lib/references.ts) of the
field's giants — Munzner, Knaflic, Tufte, Cairo, Few, Cleveland & McGill,
Wilke, Healy, Calling Bullshit, data-to-viz, Junk Charts, Spurious
Correlations, FT Visual Vocabulary — cited per sin with a relevance note
- "Don't take our word for it" receipts block on each sin
- /canon page: the full annotated bibliography
- Share control: copy-link "send them the receipt" (progressive enhancement)
- Restructured sin page: poke -> proof -> why -> receipts -> share
- Header nav (Sins / Canon); homepage reframed to the "send the link" mission
Also fix the truncated-axis bad chart: clamp the [90,100] domain so the bar
baseline doesn't overflow thousands of pixels off-canvas.

Adopt Carbon at the design-token level (the component libraries ship JS and
target app UIs; this is a static content site):
- IBM Plex Sans/Mono, self-hosted via @fontsource (no external requests)
- Carbon color tokens + layered White / Gray 100 themes
- 8px spacing scale, productive/expressive type, motion tokens, square
geometry, 2px focus ring
- UI-shell header, tile grid, Carbon tags, geometric severity meter,
breadcrumb, colophon crediting Carbon
- Charts themed with IBM Plex + Carbon's data-visualization palette
(validated colorblind-safe/contrast) on a fixed light canvas so the
build-time SVG stays legible in both themes

Set up the static-site tech stack: Astro 5 with Markdown content
collections, Vega-Lite specs rendered to static SVG at build time
(zero client JS), plain scoped CSS, and a GitHub Pages deploy workflow.
Includes three sample sins (truncated y-axis, dual-axis deception,
pie chart overload), each with a bad and fixed chart spec, plus a
gallery index and per-sin detail pages.
