/* ---- Single intended theme ----------------------------------------------
   This app has one deliberate look: the warm two-tone studio above (cream
   chrome, charcoal control rail, painted canvas). It has no dedicated dark
   theme — the inherited dark-mode variables only left light text on the
   hardcoded cream chrome. So we render the studio palette in every theme
   state (OS dark preference or a stored toggle) and hide the dead toggle.
   The control rail keeps its own dark palette (defined on .rail). */
