/* Wohnungsscanner Dinslaken — one stylesheet, no build step.
 *
 * Two genuinely different interfaces over one set of DOM:
 *
 *   desktop  a table. You are comparing 156 rows, and that is what tables do.
 *   phone    a feed of price-first cards. You are triaging on a bus with
 *            twenty seconds, and a fifteen-column table reflowed into
 *            fifteen label/value lines is 449px and 86 screens of scrolling.
 *
 * The type choice that matters here is numeric: every figure is tabular so
 * that rents line up down the column and can be compared without reading.
 * No webfont — this is opened on cellular, and a triage tool that waits on a
 * font download has already failed at its one job.
