Schedule (1f): the weekday header is S M T W T F S, the month grid is padded
for Sunday-first (Sep 2026 starts Tuesday), the anchor reads "Sunday, Sep 6",
and the single "Presence pattern" card becomes a multi-pattern "Presence
patterns" list (one child shown with two patterns) with an Add affordance.
Tasks (1e): the edit sheet gains a Start date field between Due time and Window.
Regenerates admin-1e-tasks and admin-1f-schedule (img/ and
design/examples/img/). The design-doc HTML (index.html and NestQuest Mockups.dc.html)
is edited in place; the doc's icon set has no plain "calendar", so the Start
date field is a plain value box.
