/**
 * BK ClinicQ: the patient and board layouts (Issue 5).
 *
 * The dashboard layout is the kernel console and is styled by admin.css. These two frames sit
 * beside it and read the same tokens from site.css: they differ in width, density and which step
 * of the type scale their text reads, never in colour. So a clinic's brand green, its dark theme
 * and its contrast are decided once, in site.css, for all three.
 * tests/unit/platform/test_ui_shell.py fails on a colour literal in this file.
