Goal: make the SA Element Registry dashboard actually usable. Sam reported three problems: (1) the dashboard was password protected and he wanted to know why and what the URL was, (2) when he opened the registry the elements were not viewable, (3) there was no visual preview of any element, and uploading required pasting rather than providing a file. Sam chose the path "Previews + file importer" and approved using his GitHub token. The work: build sandboxed iframe live previews (on catalog cards AND detail pages, with a desktop/mobile toggle) plus a skill-file importer (paste snippet.html / upload .zip auto-fills and creates an entry), push to GitHub so Render auto-deploys, then register the you-focus-pagebreak element through the new importer.
All build, deploy, and registration work is COMPLETE and LIVE.
Live previews: Added a buildPreviewDoc(el) function in server.js that wraps an element's stored html + css in a standalone HTML document (Poppins + Fraunces fonts, white background) and shows a friendly "No inline preview" note if the element is comment-only. Added a public GET /preview/:id route that returns that document. Added a hasRenderable(el) helper that returns true only when the html contains real tags after stripping comments. The / (catalog) and /element/:id (detail) routes now set el.renderable. On the detail page (views/detail.ejs) a live preview panel renders after the detail head, gated by el.renderable, with Desktop / Mobile / Open toggle buttons and an iframe pointing at /preview/:id using sandbox="allow-scripts allow-same-origin". On the catalog (views/index.ejs) cards now show a scaled iframe thumbnail (.thumb-frame, transform scale 0.42) when renderable, or a gradient fallback when not.
Skill importer: Added an "Import from skill" box at the top of the create form (views/form.ejs, gated so it only shows when creating, not editing). It supports drag/drop of a .zip (uses JSZip from CDN to extract SKILL.md + references/snippet.html client-side) or pasting the snippet directly. It calls POST /admin/import/parse, which returns parsed fields as JSON to pre-fill the form. There is also POST /admin/import/create which parses and inserts in one shot. Server-side helpers added: parseFrontmatter, splitSnippet, parseSnippetHeader, buildImportFields.
splitSnippet key fix: The first version got corrupted by doc-comment headers in snippet files that mention <style> or <!-- wp:html --> in prose. The fix slices from the first real block-level tag (regex matches section|div|article|etc), strips <!-- wp:html --> markers, extracts the <style> block into css and the rest into html, and trims trailing comments. This made you-focus-pagebreak parse cleanly into 832 chars of html and 1306 chars of css.
Styling: public/styles.css got .card-preview-live, .thumb-frame, .thumb-label, .preview-section/bar/toggle/stage/frame-wrap/frame, .pv-btn, and .import-box/drop/paste/actions/status. Mobile mode constrains the preview frame wrap to max-width 390px. public/app.js got the desktop/mobile toggle JS that sets a data-mode attribute on .preview-stage.
Deploy: Committed and pushed to GitHub. Latest commit 7fadeac ("Add live element previews + skill importer"), range 720377b..7fadeac on main. Render auto-deploys on push (free tier, cold start ~30-60s).
Registration: Registered you-focus-pagebreak on production via the importer at POST /admin/import/create, HTTP 200, new prod id = 36, category "Content Blocks", correct live_reference, clean 832-char html + 1306-char css.
