/* ============================================================
   v6 Pattern dialogs — Rename / Change Category / Delete
   ============================================================
   Same story as context-menu.css: PatternLibrary has always built
   this markup, but its only rules lived in the legacy style.css
   that v6 removed. With none of them loaded the overlay was
   `position: static` and transparent, so all three dialogs
   rendered as an invisible full-width strip below the fold —
   reachable from the pattern card's "More options" menu, and
   therefore dead ends.
*/

/* NOT wrapped in @layer, deliberately.
   style-v2.css is entirely unlayered and opens with
   `*, *::before, *::after { margin: 0; padding: 0 }`. Unlayered CSS beats
   LAYERED css regardless of specificity, so every padding declared inside
   @layer v6-components computes to 0 — verified in the browser against this
   file and against the pre-existing .v6-versions__menu-header. Staying
   unlayered lets normal specificity apply (.toast 0,1,0 > * 0,0,0). None of
   the selectors below appear anywhere in style-v2.css, so nothing else
   competes for them. */
