Build a modern, clean, production-ready support dashboard page for "Relay", a helpdesk product used by customer support teams at B2B SaaS companies.

Technical requirements: a single self-contained HTML file with inline CSS and JS. No external resources (no CDNs, web fonts, or images); draw any charts yourself with inline SVG or canvas. Desktop-first (designed for a 1440px-wide screen) but should not break on smaller screens. Use only the data below; do not invent additional metrics.

Who uses this page and why: Nadia is the support shift lead. It is Monday 9:05 AM and she has just opened Relay. She has about ten minutes before the 9:30 standup, and the busy US East Coast hours start at 10:00. She is opening the page to decide what to change in today's staffing and ticket assignments before the day gets away from her.

The most important question the page has to answer for her: is the team about to fall behind in a way that will hurt customers, what is driving it, and what should she do first. Everything on the page should help her make that call and take the next action. Structure the page from her task, not from a typical dashboard template.

You do not have to show all of the information below. Anything that does not help her decide or act can be merged, de-emphasized, or left out entirely. Use judgment about what deserves her attention.

Information available (use what helps): summary KPIs, ticket volume trend (7 days), open tickets by channel, top issue tags (24h), backlog by age, incoming forecast vs. team capacity (next 4 hours), agent workload and status, SLA-critical tickets, most recent incoming tickets, ticket status breakdown, daily CSAT.

Available action: Assign / Reassign a ticket to an agent. It can be a front-end-only mock (pick an agent, the UI updates).
