   <style id="nk-side-css"> block (PUBUX1-ST2) so /chat renders identically,
   now shared by every _chat_side.html includer (chat + home). ST2 additions
   at the bottom: disabled items, anon badge, generic non-chat page offset. */

/* PUBUX1-ST2-20260826-MARKER: THE one sidebar (T4 threads folded into the
   nk-side shape, [T] RULED; ACCTT4 block retired with its aside). Fixed
   full-height; .chat-surface offsets only while open (body.nk-side-on).
   T5 fix: closed = FULLY hidden -- never the half-open rail [T] flagged.
   Tokens with honest literal fallbacks (nika-tokens.css loaded above).
   Under 980px the open sidebar OVERLAYS (no push) -- mobile chat stays full
   width and the floating open button is the way in. */
