/* =========================================================================
   patent-card — v1.4 (2026-04-25). Extends v1.3 with a `private` variant.
   Sources all color, type, spacing, rule weights from webshield-navy.css.
   No new tokens, no literal hex values.

   Three variants:
     • .ws-pc              standard — for non-featured published cards
     • .ws-pc--featured    featured — for the granted patent (#1)
     • .ws-pc--private     NEW v1.4 — for QPIIN-gated cards (#2 CIP, #3 PNX)

   Status chip palette:
     granted     → FILLED gold
     pending     → OUTLINED navy
     provisional → OUTLINED muted
     private     → OUTLINED-DASHED muted (NEW v1.4)

   Private variant visual treatment:
     • surface-2 background (the inset surface — same as featured but
       without the gold top rule).
     • 1px DASHED rule border (vs 1px solid on standard) — telegraphs
       "this exists but is not fully published" without language.
     • Title color softens to --ws-ink-muted (vs --ws-ink on standard);
       weight stays 500.
     • Suppressed at the JSX layer: identifiers row, dates row, download
       slot, externalLink slot, reading-note slot.
     • New action slot (.ws-pc__actions--qpiin) for the single QPIIN CTA.
