chromelessinput: a single switch that hides the toolbar and sidebar so the
viewer shows just the scrolling pages — an embedded/inline preview mode. It is
shorthand forshowToolbar=false+showSidebar=falseand overrides them
without mutating those bindings, so toggling it off restores them. Reach for
pageOverlayTplwhen you need per-page DOM in the host app.
