/* Organdle: "Clinic & lab". A pale chart-paper page with a faint grid, ward-style mono labels, blood-tube-cap colours
   for the three modes, specimen-label hint chips, strong same/close/no-match cells (check / approx marks, hatching
   for "close") and the result as a lab report. The brand is the red kidney-bean wordmark (its colours stay the same).
   Fonts (self-hosted, SIL OFL, see fonts/OFL-IBMPlex.txt): IBM Plex Sans, IBM Plex Sans Condensed, IBM Plex Mono.
   The wordmark's letters are paths (Bricolage Grotesque ExtraBold, SIL OFL), so it needs no font of its own. */
