/* ===================================================================
   V1 STAGE 8 — THE INTELLIGENCE NETWORK DIRECTORY

   ~191 registered sources, so density is the design constraint. Each
   entry is one to three compact metadata lines carried by typography
   and hairlines — not a card, not a tile, and never a miniature
   dashboard. Anything absent is omitted rather than printed as a zero,
   because most of the registry is legitimately quiet.

   SPECIFICITY NOTE — WHY THESE BUTTONS CARRY `.btn-flagship`.

   components.css styles buttons with `button:not(.a):not(.b)...` — seven
   :not() clauses, specificity (0,7,1). That beats ANY ordinary class
   rule a feature stylesheet can write: a `.content-sources` prefix only reaches
   (0,2,0), so it loses on every property the primitive also sets.

   Stage 8 measured this live and found the Apply button rendering in the
   primitive's grey instead of its own accent — the rules below were
   correct and simply never applied. The fix is not more specificity, it
   is to stop matching the primitive: `.btn-flagship` is a clause in that
   :not() chain, so a button carrying it is styled here and nowhere else.
   Every rule below must therefore be complete on its own.
