One table column: a solution name and the store refs its numbers are
read under (e.g. hintful → android (+ any fallback), a rival →
android-scv, never inheriting another solution's numbers).
The consumer-owned content of the section (manifest readme:). The
package renders the table machinery; the consumer writes the marketing
copy (intro, footnote, image, stamp).
README markers delimiting the rendered block (HTML comments, so the
section stays invisible in rendered markdown and existing sections
migrate without touching the surrounding prose).
Renders the whole README section for content: markers, heading,
intro, the metric table (one row per publishable def, cells read from
the store via store, default benchmarks.json in the cwd), footnote,
image and stamp.
