This guide covers authored tooltips; the HTML `title` attribute produces a browser-controlled tooltip with different behavior and limitations (see below). Use the project's `skills/bug-reporting/SKILL.md` severity/priority framework to grade findings. The severity scale below is a skill-local shorthand, not a universal standard. --- ## Severity Scale (this skill) | Level | Meaning | | --- | --- | | **Critical** | Tooltip contains essential information with no other access route | | **Serious** | Tooltip unreachable by keyboard or AT; interactive content trapped in a tooltip | | **Moderate** | Tooltip accessible but WCAG 1.4.13 requirements not f
