/* ================= sf-* component kit (Phase 0, DESIGN-qaqc §2.2.5) =========
   The generic half of the LOTO module's injected stylesheet, promoted here so
   a second module (qaqc) reuses it instead of copying it: cards, tables,
   toolbars, scan strips, chips/badges, form rows, tabs, banners, segmented
   controls, side panel, kv lists, the signature pad.

   NOTHING IS RESTYLED.  Each rule below carries BOTH the new `sf-` selector
   and the `lt-` selector it was moved from, with identical declarations — the
   rendered result is byte-for-byte the same page.  What was LOTO-specific
   (the .lt-root shell, .lt-btn, status pills, the diagram/step/calendar/
   inventory artwork) stayed behind in loto.js.

   The tokens are scoped to the module root, NOT to :root, exactly as the
   `--lt-*` set always was.  That matters: `lt-`/`sf-` markup rendered inside a
   modal (which ui.js appends to document.body, outside the module root)
   resolves these to nothing and falls back to the page defaults — which is
   what the shipped UI already did, so promoting these rules changes nothing.
   A module page wraps its content in `.sf-root` to opt in. */
