/* print-tracker
 *
 * Two rules in here pull against each other and both are deliberate:
 *
 *   TYPE IS SIZED IN rem.  Page zoom scales px, so a px-only stylesheet does
 *   nothing at all for a reader who instead raised their browser's or phone's
 *   default text size — a different setting, and a common one among exactly the
 *   people who need it. `check-textsize.mjs` gates this.
 *
 *   TOUCH TARGETS ARE SIZED IN px.  A finger does not get bigger when text does.
 *   A 44px floor written as 2.75rem doubles every control at 200% text, and the
 *   target-size check goes GREENER as that happens, because 88 is further above a
 *   floor of 44 than 44 is. Elsewhere that single token pushed an app's main
 *   instrument 707px down a 640px screen.
 *
 * MEDIA-QUERY THRESHOLDS ARE ALSO IN px, because `rem` inside a media query
 * resolves against the INITIAL root font size rather than the reader's, so a
 * breakpoint written for the 200%-text case never matches.
 *
 * Colours come from palettes/3d-printing-pal.json and are measured by the hub's
 * palette gate. Dimmed text uses a colour TOKEN, never `opacity` — an opacity is
 * invisible to a contrast gate, which is how a build stamp measured 2.54:1 to a
 * reader while its gate read 4.79 and passed.
