{# FOUC-prevention: resolve theme preference and apply data-theme to
before any stylesheet loads. Reads localStorage first (client cache),
then falls back to the server-rendered ProfileSettings.theme, then to
'system'. The matchMedia listener re-applies when the OS preference
flips while the page is open AND the user has 'system' selected.
`_ps_global` is reused by the topbar `_ps` set below so the route only
hits the DB once per render. #}
