/* ── Dashboard style-preview modal: JsonRenderer baseline (deck-engine.css mirror) ──
   The style-preview modal (window.openStylePreview, dashboard.html L918) renders
   sample deck.json slides DIRECTLY into the dashboard DOM via JsonRenderer — not
   an iframe — and dashboard.html intentionally does NOT load deck-engine.css to
   keep its main-page namespace clean. Net effect: figma-sample slides rendered
   inside .style-modal-thumb-stage are missing the four foundational rules
   JsonRenderer's output depends on. Mirror just those four here, tightly scoped.

   1. `.slide { container-type: size }` — JsonRenderer emits font-size as
      `max(Npx, Ncqw)`. cqw resolves against the nearest ancestor with
      container-type, and figma samples don't wrap in .slide-scale-inner. Without
      this, cqw falls back to viewport → fontSize=40 becomes ~25px instead of
      40px-at-1920px-stage, and long lines (e.g. bold-forms slide 7 description)
      visibly overflow the text box in the scaled thumbnail.
   2. `.obj-image { overflow: hidden; border-radius: 8px }` — JsonRenderer sets
      `el.style.borderRadius` inline (e.g. "0 136 136 0" on bold-forms slide 6
      visibility image) but doesn't set overflow. Without overflow:hidden the
      child <img> isn't clipped → multi-value radii render as straight corners.
   3. `.obj-text-content` wrap rules — JsonRenderer's per-element overflow-wrap
      catches long-word break but pre-wrap whitespace handling lives here.
   4. `.deck-object` position — JsonRenderer adds `position:absolute` inline so
      not strictly required, but mirrored for parity with editor/viewer paint.

   Source of truth: deck-engine.css §JSON-RENDERED OBJECTS (L339, L1978-2010).
