Below lg the top bar now holds the brand and one toggler; the account
items render in the drawer as a second, labelled list from a shared
partial, so both surfaces cannot drift. Desktop unchanged.
Extract the top bar and account menu into shell_topbar.html and the
member rail into shell_rail_member.html, backed by a single
server.Shell value. Move session controls into the account menu, add
the mirrored Operator panel/Member dashboard surface switch, and turn
the rail into an offcanvas drawer below lg with shell.js closing it on
navigation. Update docs, specs, and tests.
Unify application shell across both surfaces
Extract the top bar and member rail into shared partials and introduce
server.Shell as the single data value for page chrome. Move session
controls into an account menu, make the rail an offcanvas drawer below
lg, and add the mirrored surface switch.
