Add shared/sx/html_to_sx.py (HTMLParser-based HTML→sx converter) and update lexical_to_sx.py so HTML cards, markdown cards, and captions all produce native sx expressions instead of opaque HTML strings. - ~kg-html now wraps native sx children (editor can identify the block) - New ~kg-md component for markdown card blocks - Captions are sx expressions, not escaped HTML strings - kg_cards.sx: replace (raw! caption) with direct caption rendering - sx-editor.js: htmlToSx() via DOMParser, serializeInline for captions, _childrenSx for ~kg-html/~kg-md, new kg-md edit UI - Migration script (blog/scripts/migrate_sx_html.py) to re-convert stored sx_content from lexical source Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

/**
|
|
* SX Block Editor — a Ghost/Koenig-style block editor that stores sx source.
|
|
*
|
|
* Matches Koenig's UX: single hover + button on empty paragraphs, slash
|
|
* commands, full card edit modes, inline format toolbar, keyboard shortcuts,
|
|
* drag-drop uploads, oEmbed/bookmark metadata fetching.
|
|
*
|
|
* Usage:
|
|
* var handle = SxEditor.mount('sx-editor', {
|
|
* initialSx: '(<> (p "Hello") (h2 "Title"))',
|
|
* csrfToken: '...',
|
|
* uploadUrls: { image: '/upload/image', media: '/upload/media', file: '/upload/file' },
|
|
* oembedUrl: '/api/oembed',
|
|
* onChange: function(sx) { ... }
|
|
* });
|
|
* handle.getSx(); // current sx source
|
|
* handle.destroy(); // teardown
