/**
 * The dashboard's source, for the guards that pin how it is wired.
 *
 * The dashboard is a composer (`src/app/page-client.tsx`) over a tile
 * registry (`src/components/dashboard/tiles/`): the reads, the tile context,
 * the strip and chart definitions and the rendering of both rows each live in
 * their own module there. A guard that used to read the one page file reads
 * all of them through here, so a rule about the dashboard holds wherever in
 * the registry the code it watches sits, and moving code between the files
 * cannot turn a negative assertion green. The folder read carries a floor,
 * and the page read an anchor, so a rename fails loudly instead of returning
 * less text.
