Follows the pulse / pulse_dev split. 274.md keeps the frontmatter, the
intro and the lyrics workspace; everything below moves to 274-dev.md,
which will document how the PoI candidates were assembled and hold the
filtered charts.
Uses the new relative-Markdown-link convention rather than a siblings
macro, in both directions. Dev page carries publish: false to match
274.md while both are under wip/.
Contents moved verbatim; the dev page's own prose is still to be written.
