/* ===================================================================
   Signal  —  sig / --sig-
   Confident television. A crisp white studio field, PBS blue at full
   strength as structure, a thin SMPTE seven-bar signature rule, mono
   channel numerals, and a lower-third caption pattern.

   One of three sibling kits for newnjpbs.org. Namespaced sig- / --sig-
   so it never collides with gs- (Garden State public) or post- (Garden
   State poster) on the chooser page.

   Tokens live on :root. Base typography applies under .sig.
   Components carry their own look and work inside .sig. Light is the
   default; dark is opt-in via [data-sig-theme="dark"] or .sig-dark.

   Craft rules (shared house style): sharp corners (no border-radius on
   components), uniform hairline borders, shared-border grids, callouts
   by tint + title color (never an edge stripe), section heads with a
   mono number + flush-right meta. No eyebrow kickers, no gradient text.
