Formatters

TypographyFormatter

Trek::TypographyFormatter applies French typography rules to strings and ProseMirror documents (only text nodes are modified):

• non-breaking spaces before : ; ! ? % € $ » and after «, dashes, n°
• non-breaking spaces before units (km, kg, h, min, °C…) and between digit groups
• ... → …, ASCII apostrophes → typographic '
• removes double spaces and spaces before periods/commas

Wire it to attributes with Formattable:

include Trek::Formattable
format_attributes Trek::TypographyFormatter, :title

ProseMirror → HTML pipeline

formatted_content (from Contentable) renders ProseMirror JSON to safe HTML through the prosemirror_to_html gem, extended with:

Piece	Role
Nodes::ImageBlock	renders image_block nodes as figures (Shrine image, alt, caption, size)
Nodes::PromptsBlock	renders prompts_block nodes as call-to-action buttons
RemoveEmptyParagraphsFormatter	strips empty <p></p> tags
GlobalIdToLinksFormatter	resolves gid:// references in links to real record URLs

The pipeline is orchestrated by the Prosemirror model — extend it with your own node renderers when you add custom blocks to the editor.
