Add an example

What an example is

An example is a concrete, honest walkthrough of something the substrate makes possible — marked clearly for what is real today versus still a sketch. Examples drive the /examples index, the per-example pages, and the "Examples involving this system" sections on /systems/<name>.

Steps

1. Create the file site/content/examples/<slug>.md.

2. Write the frontmatter — note stage and systems:

   ---
   title: Late-bound use
   summary: One sentence for the card.
   stage: partial          # today | partial | sketch | candidate
   systems: [ontos, logos, thesmos, horos]
   tldr: A one-line reality check rendered as a callout before the essay.
   ---
   
   ## The walkthrough
   ...
   

3. Pick the stage honestly — today (works now), partial (partly real), sketch (vision), candidate (candidate theory). It renders as a status badge and tones the callout.

4. Lint + preview:

   node bin/atlas.mjs site lint --strict
   npm --prefix site run build
   

Notes

• Every name in systems: must be a real member, and stage must be one of the four values — site lint enforces both.
• The example automatically appears on each system page it names; no extra wiring.
