 * the buttons sit side by side instead of on top of each other.
 *
 * Colours now match .tb-pill-btn. The old rules painted it white-on-white:

/* ── AI engine badge ─────────────────────────────────────────────────
   Small "AI engine · <model>" pill that lives inside every AI-gen
   modal (dashboard GenerateModal, editor AddSlideModal, editor
   AIReplaceModal) directly under the primary Generate button. Tells
   the user which backend actually runs the generation, and gives
   Rainy a visible smoke-test that a model swap landed.

   Shared class so all three modals look identical. Kept in blocks.css
   (loaded by both dashboard.html and editor.html) so a modal doesn't
   have to inject its own copy of the styles.

   JS updates the model text via `#ai-engine-badge-model` fetches to
   `/models`; the SSR-safe hard-coded fallback in each modal keeps the
   pill readable if the sidecar is unreachable. (Rainy 2026-07-02.) */

   badge → dropdown so user can pick Claude / GPT-5 per generation.) */
