{#- The node's maintenance card (ADR-0014): the current pin, and the admin
    read/edit/clear controls. Shared by the leaf detail page (check.html) and the subtree
    page (status.html): the model, POST /maintenance, persistence and the reaper
    always accepted a container pin; this partial is the surface for it.
    The caller gates on `is_admin`; `maintenance_default` is the
    deployment's default window (settings.yaml), shown so a blank field says
    what it means. The wording carries the feature: today's pin silences
    *everything*, so the sentence says exactly that — and stays honest about
    what keeps running underneath.

    A **pinned** node opens in read mode: the reason is safe rendered Markdown,
    then an explicit Edit disclosure reveals the raw source in a textarea
    (ADR-0014 / ADR-0018 amendments). Extending a window therefore remains an
    in-place edit, never a clear and re-set. Duration is *not* prefilled: blank
    means the configured default here exactly as it does on an unpinned node.

    This is also where the pin's full four-field reading lives — pinned by whom
    and when, last changed by whom and when — because there is room for it here
    and not in the popover.

    Both forms carry the entry's `set_at` as the compare-and-set token; empty
    says "I believe nothing is pinned". A write whose token no longer matches is
    refused whole and comes back as the conflict page. -#}
