ConvertContentH1 rewrites content only when it is HTML; a markdown
source, its code samples included, is kept byte for byte and only its
rendered content_html is converted, on API saves, imports,
journal:fix-headings and translations. ConvertH1 and SetImageAlt keep
the bytes of an unfinished tag at the end of the input.
- ConvertContentH1 and ConvertTranslationH1 for post bodies and category
pillar text
- SetImageAlt with several matches, repeated alt attributes and markup
that only looks like an img
- the content facts outline, images, decorative images and embeds
- the related-posts mode and count
- content_h1_to_h2 and generic_anchors on the settings row (migration
202610280001), Headings and links tab, config key
golem15.journal.content_h1_to_h2 used when no settings row exists
- classes.ConvertH1 on the x/net/html tokenizer; the Blog Editor types
convert while the setting is on and answer editor.h1_converted
- GET /posts/{slug} reports content_h1_to_h2 (additive key)
