Task 628: Add <main> Landmark to HTML Template

Status: DONE

Problem

The HTML template in templates.ts wraps page content without a <main> landmark element. Screen readers and keyboard navigation tools rely on landmarks (<main>, <nav>, <footer>) to help users jump between page sections. The template already has <nav> and <footer> but is missing <main>.

Solution

Wrap the main content area in a <main> element in the layout template function in templates.ts. Added E2E test verifying nav, main, and footer landmarks are present.

Files Modified

• ts/src/templates.ts — Wrapped content in <main> tag
• ts/e2e/reports.spec.ts — Added semantic landmarks E2E test
