/* side-panel.css (console copy) — the two side panels, one grammar: the
   Rooms panel on the LEFT edge (navigation, account — the shell's own
   sidebar markup) and the Explorer panel on the RIGHT edge (the
   workbench's file tree and search).

     HIDDEN   only a slim vertical tab on the panel's own edge (44 px hand)
     OPEN     slides in over the content; auto-hides 2.5 s after the pointer
              leaves it, on Esc, on a press outside, after a room is chosen
     PINNED   docked: the main column yields by the panel width on that
              side and it never auto-hides until unpinned

   State is carried on <aside data-side data-state="hidden|open|pinned">
   and mirrored on <html class="sp-left-pinned sp-right-pinned …">. Every
   colour is one of the console's own tokens (--panel, --border, --text,
   --accent, --kit-seal). Loaded AFTER console.css and builder.css: the
   rules below replace console.css's own fixed/sticky sidebar. Phone first
   (375×812); desk and tablet inherit. Built by js/shared/side-panel.js. */
