A section heading (h2)
Placeholder: this is where the article’s first section starts. Regular paragraphs are just markdown — write normally, no escaping needed for the custom-element tags further down.
A subsection heading (h3)
Placeholder: use h3 for a subsection inside the h2 above.
A plain list, for steps or a set of related points:
- Placeholder first point.
- Placeholder second point, can run longer to show how wrapping looks in the ~70ch prose column.
- Placeholder third point.
Placeholder callout. A blockquote doubles as the callout style — use it for asides, warnings, or “why this matters” notes that should stand out from the surrounding prose.
A fenced code block:

a real article):
Embedding the sample player
Placeholder: this is the pattern for an in-article audio comparison —
drop the tags below verbatim and point src at files under
public/audio/articles/.
Visualizing harmonic content
Placeholder: this is the pattern for comparing sources’ per-partial
harmonic composition and harmonic ceiling — drop the tags below verbatim,
same <sample-src> children as the sample player above.
Visualizing signal properties
Placeholder: this is the pattern for comparing sources’ envelope, crest
factor, and spectral flux over time — again, the same <sample-src>
children.
