/* リハビリ職のみちさき案内 — Phase 0/P2 base styles.
   Theme: 静かなキャリア案内所. Restrained visual system per Phase 0 scope
   (template/nav spec section 7): no ranking cues, no image-heavy hero,
   calm whitespace, white ground with a quiet blue-green accent. Phase P2
   adds: readable width hierarchy on Top, a zero-JS mobile nav disclosure,
   lightweight (non-card) section grouping for Top's 5 entry points, and a
   clearer visual split between body links / Related Links / Official
   Information Link so the last never reads as an affiliate-style CTA. */
