-------------------------------------------------------------------- NOTES -------------------------------------------------------------------- This is deliberately short. Your theme already outputs og:title, og:description, og:url, og:site_name, twitter:card, twitter:title and twitter:description through the social-meta-tags snippet, and it already outputs a canonical tag. Adding those again would duplicate them, and the browser takes the first one anyway. The two things it does NOT do: 1. There is no robots meta anywhere. Adding max-snippet:-1 and max-image-preview:large    tells Google it may quote the full answer block and show the diagram large. That is    what wins the AI Overview and the image result. 2. social-meta-tags only emits og:image for products and for articles that have a    featured image. Pages get no image at all, so the guide pages currently share as a    bare link. The block above fixes that for the two guide pages. Once the diagram PNG is uploaded to Shopify Files, replace all three instances of REPLACE_WITH_DIAGRAM_CDN_URL with its CDN URL. Until then, leave the second block out. For the touchmark post, set a featured image on the article and the theme handles the og:image on its own. Nothing to add.

## Key facts

- Stamp size means character height, measured center to center of the top and bottom
  strokes of the character.
- A stamped impression is always larger than the stamp that made it, typically by 10
  to 20 percent on mild steel, because struck material flows up the tapered flanks of
  the character.
- Standard character heights run 1/32 inch to 1 inch, roughly 0.8 mm to 25.4 mm.
- Character size does not change with material. Impression spread does.
- Line length is roughly the number of characters times the character height times
  0.75.
- Baseline to baseline spacing on multi-line work is 1.5 to 2 times the character
  height.
