Three jsdom axe scans covering the user-facing surface of the canvas.
The scans surfaced two real a11y bugs which are fixed in this same
commit:
1. PerformancePopover — VProgressLinear (advancing aggregate) had no
accessible name. Added aria-label that announces "X van Y secties
afgerond (N%)".
2. AddPerformanceDialog — the icon-only close button (×) was missing
aria-label. Added 'Sluiten'.
Test scenarios:
- PerformanceBlock with focus
- PerformancePopover open
- AddPerformanceDialog open
Page-level axe rules (region, page-has-heading-one, landmark-one-main,
color-contrast) are disabled for fragment scans — they only make sense
on a full page, and color-contrast resolution is jsdom-blind. Both are
covered by Playwright CT in TEST-INFRA-001 / TEST-VISUAL-001.
Test count: 380 → 383.
