"""Every modal sheet is a real centered overlay — not an unstyled block in flow.

inbox, diff, board and broadcast are dialogs that open over the app. They each
need the overlay rule (`position: fixed`, a scrim, centred) that #settings and
#keys have. They once shipped without it and rendered as full-width unstyled
strips at the foot of the page — the board fell entirely below the fold — yet
the per-feature Playwright checks passed, because Playwright drives an element
by DOM ref no matter where it renders. This asserts the CSS itself, so that
class of "the button does nothing / breaks the UI" bug cannot come back unseen.

Needs the Playwright venv:

    ~/.cache/clique-visual/bin/python tools/overlays_check.py

Exit status is 0 on pass, 1 on fail.
