Context files, PDF support & a rebuilt onboarding

✨ New Features

• Context files replace playbooks. Tell GitLaw your positions and preferences once, and it applies them to every document it touches.
• PDFs now open as PDFs. GitLaw only converts one when you start editing.
• Import files straight from Google Drive.

🔧 Improvements

• Rebuilt onboarding, so you're set up and drafting faster.
• Redesigned sharing end to end: a clearer share modal, a proper landing page for whoever you send documents to, and a send-back path so they can return their changes.
• Starter prompts now match your jurisdiction.
• "Help me decide" opens a guided wizard when you're not sure which document you need.
• Added a press releases section, and made GitLaw pages render properly for search engines and AI assistants.

🐞 Fixes

• The editor holds your scroll position when you save redline changes.
• The notification badge now only counts alerts that have something to show.
• Documents waiting on a signature show that status in the document info panel.
• Fixed nested folder listings, template scrolling, and toolbar focus.
