/*
 * Motor Trade - the whole-page shell: navy left sidebar, white top bar, content
 * slot. Styles lib/ui-motor-shell.js and nothing else.
 *
 * Every value here was measured off design/reference/01-market-neutral.png and
 * 02-warehouse-preview.png (sidebar navy #102a3a, ~249px wide; active nav block
 * #00858f spanning the full sidebar width; top bar 66px over a #ebedf0 hairline;
 * content #f8f8f6; slate avatar fill; bright teal strapline rule).
 *
 * Every selector sits under `.msh-shell` and every class is prefixed `msh-`,
 * every custom property `--msh-`, so this file cannot reach the content styled
 * by styles/motor-sales-ops.css (`mui-`) or styles/motor-ceo-finance.css
 * (`mceo-`), and neither of those can reach the frame.
 *
 * ONE accent (teal). Monochrome line icons drawn in currentColor. No emoji, no
 * gradients, no animation, no second accent.
