Two new levers on a sin page. `wild[]` renders credited, linked
specimens between the explanation and the citations — first the
argument, then proof people actually publish this, then the sources.
`related[]` cross-links neighbouring sins and is resolved at build, so a
typo fails the build instead of shipping a dead link.
Both arrive with the first specimen: a Hungarian primary graphic whose
three slices read 38/22/19 — 79% — drawn as a full circle, so every
share is inflated by about 1.27x. Measured off the image, the 38% slice
occupies 173.6 degrees, or 48.3% of the pie.
Our published pie sin is about too many slices, so it didn't cover this;
"Pie Slices That Don't Sum to the Whole" is a new severity-5 page whose
before/after is two pies differing only in whether the remainder is
present. That sin is an omission, so `compareNote` replaces the standard
"same numbers, both charts" line.

"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.

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.

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.
