28-Jul-2026 — H1–H6 headings and extract TipTap/composer helpers ref #303

build 801 — commit 004a302

What's new

The shared TipTap editor now supports the full set of heading levels used on the site (Heading 1 through Heading 6), so existing content and paste that use any of those levels keep working in the toolbar and in the document. Styles for the editor live in a dedicated stylesheet next to the component, and paste clean-up helpers are shared pure functions rather than buried in the component class.

Email composer helpers that used to sit in the model file (merge-field labels, example values, divider HTML, default fragment order, and related builders) now live under functions/, so the model keeps types, enums and catalogues only.

At a glance

• Toolbar offers Heading 1–6 plus Normal text
• TipTap StarterKit accepts heading levels 1–6 (matches content already stored on sites)
• Editor styles moved out of the TypeScript file into tiptap-markdown-editor.sass
• Paste sanitisation for HTML and markdown is in tiptap-paste.ts
• Merge-field brace stripping is shared (stripMergeFieldBraces) so insert and edit paths stay consistent
• Friendly labels and example values for merge fields and link tokens come from functions/merge-fields.ts
• Divider HTML, fragment builders, recycled-tracking URL scan and default composer state come from functions/email-composer.ts
• Fragment-order state fields are named via EmailComposerFragmentOrderField instead of an ad hoc string union
