dataviz-inspiration

Add a new data-visualization entry to the dataviz-inspiration gallery. Use when the user pastes messy content (a link, screenshots, notes) about a viz and wants it added to the site. Handles the viz-list.ts entry, image placement, chart-type tagging, and the two descriptions.

Draft a LinkedIn post announcing the latest data-viz additions to dataviz-inspiration.com, and stage the highlighted projects' images in public/linkedin/. Use when the user wants to share the last batch of new gallery entries on LinkedIn.
