design: in-log, Why is a sheet over the page; no Deny on a Postfix reject

Owner, 2026-10-11/12, on the Inbound log as built:
  - "Why сделать не столбцом, а листом поверх." Opened by the decision
    tag ("Тег."), drawn first, then: its content as a table ("В лист
    может быть таблицей?" - "Да. Но хорошо бы ещё её отцентрировать."),
    with a narrow column of names and only what the row does not show.
  - "Почему Deny у того, кто rejected?" - "Убирай": a message Postfix
    itself refused offers no Deny sender. Accepted mail offers Deny,
    mail the filter refused offers Allow.

A new component, sheet (theme.css, shown on the components page next to
status_tag): the browser's own popover, so no script - the tag is a
button with popovertarget; Esc, a click outside and the cross close it.
It rises from the bottom edge across the window; its content is a table
of name and value in a 44rem column in the middle. A tag that opens a
sheet carries a dotted underline to tell it from a plain tag.

in-log: the Why column is gone and rows are one height. A sheet holds
who decided, the verdict and the symbols (or the reply), and the
subject whole.

Guard: check.py WIDTH_OK gains ".sp-sheet" - the one component laid out
by the window and not by the page. The owner accepted the drawing with
that said.

check.py: 32 screens, 52 sp- classes, 0 violations; outlines.json
unchanged.
