	2	* AI Technical Debt Map.
	3	*
	4	* Routes:
	5	* GET /:owner/:repo/debt-map — render the interactive graph page
	6	* POST /:owner/:repo/debt-map/analyze — trigger analysis (owner only), returns JSON
	7	* GET /:owner/:repo/debt-map/data — return DebtReport JSON
	8	*
	9	* The page renders a Canvas-based force-directed graph where:
	10	* - Node radius = sqrt(lines), capped 6–30 px
	11	* - Node colour = debt score (green → yellow → red)
	12	* - Edges = import relationships
	13	* - Click a node = side panel with Claude's debt analysis
	14	*
	15	* Analysis is asynchronous: the POST kicks off a background Bun promise and
	16	* returns {status:"running"}; the GET /data endpoint returns the cached
	17	* report (or 202 if still running).
