/*
  薬剤師のみちさき案内 — Phase 0B-2 Visual Foundation.

  Two token layers, kept separate on purpose:
  - Common Brand Layer: neutrals, spacing, radius, widths, type. Reusable
    across any future "みちさき案内" profession line.
  - Profession Accent Layer: everything pharmacist-specific (accent color,
    hero motif tone). Swap only this block to re-skin for another
    profession — nothing else should need to change.

  Restrained on purpose: no medical-blue, no primary green, no strong cyan,
  no loud gradients, no dark hero. No external framework, no web fonts.
