v0.15.0

Features

• Link Paste — Pasting a URL now offers a Notion-style menu to keep it as a link, or convert it into a Bookmark card or rich Embed block. The pasted link shows immediately with the menu anchored at its end, and menu labels name the detected link type via provider metadata.
• Embed — Worldwide embed registry covering ~115 services across video, audio, social, documents, design and developer domains, including Google published docs/forms and draw.io. Per-source minimum resize widths keep each provider's iframe legible, and fixed-width providers hug their content with figure, handles and toolbar.
• Bookmark — Notion-parity bookmark card with a dev unfurl endpoint; crawler-UA retry recovers metadata from bot-blocked sites.
• Playground — Smooth cross-fade theme switching via View Transitions, plus an Airbnb-style neutral redesign.

Bug Fixes

• Embed — Preserve the live iframe across every editor action: caption and alignment toggles now apply in place instead of reloading the player. Selection highlight hugs the figure dimensions.
• Drag & Drop — FLIP-animate the column drop moment and slim the vertical drop bar to read like the horizontal line.
• Security — Harden URL-scheme filtering and neutralize XSS gaps in markdown paste, the inline link tool, and the paste/render pipeline.
• Tools — Implement setReadOnly on embed, bookmark and column tools so read-only toggles in place without a full re-render.
• Icons — Unify the icon set on the 20×20 / 1.25 house spec; refine heading family, quote, caption, pencil, cells, toggles, and numbered-list glyphs.
• CI — Pin Node 24.14.1 to dodge a Playwright install hang; share Playwright setup to stop Storybook browser install hanging; repair 6 failing CI specs (5 stale expectations, 1 real drop-indicator regression).

Maintenance

• Dependencies — Resolve all 52 open Dependabot alerts; bump brace-expansion, ws, smol-toml.
• Tests — Embed/bookmark/link stories with screenshot baselines, wave-2 embed visual-regression baselines, verified real sample URLs replacing fixtures, refreshed main.css golden snapshot.
• Docs & Playground — Embed, bookmark and link entries in tools data and the editor demo.
