- Fix noDangerouslySetInnerHtml via SanitizedHtml component
- Fix useExhaustiveDependencies in catalog-manager-dialog
- Fix noArrayIndexKey across 26 files (stable keys)
- Fix SVG a11y (titles, roles, aria-labels)
- Fix label/input associations (htmlFor/id pairs)
- Fix static element interactions (role + keyboard support)
- Fix noImgElement, noDescendingSpecificity (disabled - external Habbo URLs)
- Fix noNonNullAssertion, useTemplate, unused vars/imports
- Add SanitizedHtml shared component
- Migrate biome.json to 2.5.4 schema
