/*
 * FIELDSETS-ENV.CSS - Element-bubble system + elements-builder shell
 *
 * NOTE: filename is now a misnomer. The environment fieldset (and the
 * v11.0 slot-pair / legacy .fieldset--env theming) was removed — its
 * bubbles moved into the shared element-bubbles overlay. What's left is
 * the SOLE owner of the bubble system: .builder-tag(s) + variants,
 * .tag-* internals, .swatch-* picker, per-bubble .tag-switch, the
 * .builder-tag--frame chip, the
 * .fieldset--elements-builder shell, and the .generating .builder-tag
 * busy rules. Rendered into the chat/card overlay by element-builder.js
 * — not duplicated in any other stylesheet, so it must stay linked.
 * Follow-up: rename/relocate to e.g. element-bubbles.css under
 * carousel/css/ and drop the 5 fieldsets-env.css <link> tags.
