 * Grid/flex children default to min-width:auto, so one nowrap child — the
 * weight table's .pt labels, the cheatsheet's .cmd .c — props up its whole
 * track's min-content and the section clips at phone widths. Same donor
 * shape as the mx-checker / port-checker / traceroute cheatsheets: this file
 * was generated from the mockup BEFORE those siblings gained their fix.
