/**
* Contact Form: the "Get in touch" / "Contact sales" form, done properly.
*
* Topic chips at the top (Sales, Support, Press, Other by default) with a
* pill that slides between them; each topic reshapes the form (Sales asks
* for company and team size, Support doesn't) and the card's height glides
* to fit. A work email fills the company field from its domain
* ("dana@acme-labs.com" → "Acme Labs", marked "from your email";
* free mail never does). The message box grows as you type and only shows a
* counter near the limit.
*
* The hidden details: give it your business hours and it tells people when
* they'll actually hear back, in their own time zone ("Expect a reply by
* tomorrow, 10:00 AM"), and whether you're online right now ("Back Monday,
* 9:00 AM"). And an accidental reload never loses a half-written message:
* the draft is kept for the tab session and restored with an Undo-able note.
*
* Sending: errors sit in the label row (nothing below the field moves; an
* empty field you only tabbed past is not flagged until a send attempt), the
* bad fields shake once and the first one takes focus. While sending, the
* button holds its width (send, sending and retry labels share one cell) and
* keeps focus; then the form folds into a summary of what was sent, which
* takes focus, with the reply estimate and "Send another". A failed send
* keeps everything and offers Try again.
*
* Long topic or size lists scroll inside about seven rows (at most half the
* screen) with an edge fade; long unbroken text wraps instead of leaving the
* card. Reply times a week or more out name the date, not just the weekday.
*
* Responsive: one column under a 460px card; the card stops at 72ch
* (--contact-form-max-width) so the message keeps a readable measure; touch
* screens get 44px chips and buttons; a Tab onto the message box scrolls the
* whole box into view.
*
* Native inputs and labels underneath; the chips are radio groups with arrow
* keys; status changes are announced. No native selects. Reduced motion:
* fades instead of slides and shakes.
*
* Server rendering: pass `now` when you pass `hours`, so the status and the
* estimate render on the server. Without it they appear after mount.
*
* Corners follow --ui-radius, --ui-radius-sm, --ui-radius-pill. Theme via
* library tokens (--ui-ink, --ui-surface, --ui-accent, --ui-ok, --ui-danger)
* or --contact-form-* overrides.
*
* Requires: react >= 19, motion >= 11.
