/* BreadMind SDUI Messenger — design bundle ingestion.
   Workspace rail removed; shell collapses to topbar(44) + sidebar(280) | main(1fr) | thread(0|380).
   Tokens come from design-tokens.css (already aligned with the prototype).
   Compatibility aliases for the previous .msg / .composer / .reactions class set are kept in

/* ----------------------------------------------------------------------------
   Slot inner: neutralise the global ``.sdui-page`` wrapper.

   Every server-rendered SDUI view is wrapped in ``<div class="sdui-page">``
   by the renderer (see ``sdui.css`` ``.sdui-page``: max-width 1200px,
   margin: 0 auto, padding: 24px). Inside the messenger shell that default
   shrinks the topbar and main pane to ~600px and centres them, leaving
   huge dead bands on the right and pushing the topbar's flex row down
   ~24px so the search pill visibly overflows the 44px bar.

   Reset every ``.sdui-page`` that lands directly inside one of the four
   slots so the slot's own grid cell defines the size, and let the main
   slot carry the design's flex-column flow (header + scroll + composer)
   into its inner page wrapper as well — otherwise ``ws-scroll``'s
   ``flex: 1`` does not get a flexbox to flex inside.
