- Each option's explanation moves from a line of text under its label to
a small tooltip on an ⓘ beside it, so forms read calmer and the help is
still one hover away.
- Help text is ours where written (src/help/texts.ts: domains, people,
DNS providers, blocked addresses, and the main pages), and the schema's
description elsewhere.
- A "?" on every list and form opens a side panel: what the page is for,
what people usually do there, and every option explained.
- Every tooltip and panel carries a stable help id (x:Domain.dnsManagement,
x:Domain), and manual.ts turns an id into a link to the admin manual
once one is configured (VITE_MANUAL_URL, or <meta name="manual-url">).
Until then no link shows.
