New custom element (src/components/help-tip.js):
- Floating card appears on hover/focus, appended to document.body
(position:fixed) so it escapes overflow:hidden in the TOC sidebar
- Attributes: label (bold), description (body), doc (optional
"Learn more →" link)
- Mouse-over-card grace period so the link stays reachable
- Correct viewport clamping (horizontal + prefer-above/fallback-below)
workstreams.md:
- WHI metric abbreviations (DD/BR/SPR/PEP/CDDR) now use <help-tip>
with full name, one-sentence description, and doc link
- Domain breakdown labels show domain-scoped stats (open count,
blocked%, runnable%) and a doc link
- Cycle ⚠ icon upgraded to <help-tip> with explanation
- Removed dotted underline; cursor:help comes from the element CSS
