/* ===========================================================================
   SolutionsSales -- 仕組み (FRAGMENT:loop). Layout + FINAL state.
   A true circle: 発掘 (W) -> アプローチ (N) -> 商談 (E) -> フォロー (S) -> 発掘,
   AI core in the centre (solid product purple #805496), 営業データ feeding
   発掘 from outside. The lines (ring, rail, feed) use a lighter purple so the
   core stays the one solid purple mass.
   Each step is a rounded "button" docked on the ring: numbered badge at its
   head, role marks after its name (AI = .sa-ai from sales-ui.css, 人 = flat
   grey chip). 商談 is the person's step: no AI mark, and it lights grey/navy
   instead of the AI tint. Two exits leave the ring (dashed, paler than the
   ring): 商談 -> 受注・失注, フォロー -> ナーチャリング. They are outcomes of
   the process, drawn static (nothing travels along them).
   - >= 1200px: data column left + ring.  768-1199px: data row on top + ring.
   - < 768px: vertical stack, connector through the badges, bracket back from
     4 to 1, exits hang under 商談 / フォロー in their own grid rows (--xh).
   Everything in this file is the resting state (no JS / reduced motion):
   ring fully drawn, 4 steps equal, no moving dot. sales-loop-2.css scrubs it.
   Ring geometry lives in vars on .sa-loop-board: --cw/--ch card, --g card
   offset from the ring (negative = the card overlaps the ring = docked),
   --r ring radius, --core AI core diameter.
   Contrast: #FFF on #805496 5.79:1, #F1E6F6 on it 4.80:1; ring #9E7BB2 on
   #FFF 3.54:1; --muted on #F1F3F5 4.93:1, --navy on it 13.2:1.
