/* PCTU – Tư vấn gói khám lâm sàng (consultation page)
 * Concept: a consultant's case record. Quiet conversation, one memorable element: the decision sheet
 * (criteria → finding → verdict, then the orders and what was ruled out).
 * Palette: sage paper, pine ink of the hospital record, clinical red only for warning signs.
 * Type: Be Vietnam Pro (designed for Vietnamese diacritics).
