…mo link OpenCode plugin only read PLANNOTATOR_SHARE_URL; add a getPasteApiUrl helper and thread it into plan/annotate/archive server starts. Pi extension's serverReview gains the same shareBaseUrl/pasteApiUrl env-var pair already used by serverPlan/serverAnnotate. Landing.tsx now accepts a shareBaseUrl prop for self-hosters' demo link. Paste-service CORS defaults grow a comment clarifying that self-hosters must override ALLOWED_ORIGINS.

suggestion (blocking): This needs documentation
When PLANNOTATOR_PASTE_URL is set to a non-default paste service, the generated short link now includes a base64url-encoded paste param in the fragment (#key=...&paste=...). The share portal and importFromShareUrl extract it on load so they can fetch from the right paste backend without needing a server — fixing broken short links for self-hosters who use a custom paste service but keep the hosted share portal. Backward compatible: links without a paste param continue to use the default or server-provided paste API URL as before. For provenance purposes, this commit was AI assisted.
