/* ==========================================================================
   Sổ Thí Nghiệm Phú Thành (buiducthinh) — shared mockup stylesheet
   One file for every screen: tokens, base, shell, components, entry grid,
   A4 documents, phone frame. Plain CSS, no remote assets.

   Colour logic (PRODUCT.md: "ít màu, màu chỉ dùng để báo trạng thái"):
   - graphite neutrals tinted toward cobalt (hue 262)
   - "pen" cobalt = what a person typed (raw measurements), primary action,
     current selection. Computed values are graphite on a sunk cell.
   - "stamp" oxblood = the lab's seal: brand mark and document stamps only
     (BẢN NHÁP, ĐÃ HỦY), never a state colour.
   - verdicts: Đạt / Không đạt / Chưa đủ số liệu / Không đánh giá always carry
     a word and a differently shaped icon (circle / square / dotted circle /
     diamond), so they survive black-and-white print and colour blindness.
