/* ---- Entry button: the only way into the guide ---------------------------
   Sits directly under the Studio header.  The white tile shows the account's
   own logo (studio.js keeps <img data-studio-logo> current); accounts without
   a logo yet get the play glyph instead, and a logo tile wears a small play
   badge so the button still reads as "watch a guide". */
