[kemaldotearth]

I have read the CONTRIBUTING.md file.

YES

What kind of change does this PR introduce?

Abstracting and tidying the metric block we added during auth overview design work. This will likely be used elsewhere to display singular metrics, so componentising.

Weird build error on docs:

Module not found: Can't resolve './build/Release/queryparser.node'
> 1 | const PgQuery = require('./build/Release/queryparser.node');
    | ^
  2 |
  3 | module.exports = {
  4 |   parseQuery(query) {

Looks good! Approved but two things to probably investigate:

• Light mode text legibility
  • Non-blocking as I see it predates your work here
• Error on docs build
  • Could be unrelated or inconsequential
