chore(client): hold the complexity count at the notifications redesign's lower one

Every notification gets a tile in the colour of what it is about (a trip, a
message, a booking, packing, a to-do, Vacay, a collection, shared photos, a
tour, an update or an alert) with the sender's face on its corner, the page
and the bell's panel group the list under Today, Yesterday, the weekday or
the date, and answering or following a notification is a proper button.
The server's UTC timestamps are read as UTC for the grouping and the time.

- * ── Why every tile is a real preview ──────────────────────────────────────
+ * Four tabs, the way the Elements panel sorts what it adds: the figures, the
+ * maps with the stops they are drawn from, the countries, and the marks. Every
+ * card is the element its click places, built by the book engine and drawn by
+ * the page's own renderer with this journey's numbers in it, in the newer
+ * looks and in the book's theme (travel/travelBuilders.ts). The looks books
+ * had before these still draw on the pages that hold them; they are no longer
+ * offered here.
  *
- * These elements differ from one another by what they *say*, not by their
- * shape. Four map styles are four maps; three summary layouts are the same six
- * numbers arranged three ways. A named row with the value beside it — which is
- * what this panel was first — tells you none of that: you cannot tell the dark
- * map from the paper one, or a row of figures from a grid of them, until you
- * have placed one and undone it.
- *
- * So each tile builds the element it would place and renders it through the
- * page's own renderer, with this journey's real numbers in it. You are picking
- * from the things themselves.
- *
- * Every button resolves its values *now* and writes them into the element, so
+ * Every card resolves its values now and writes them into the element, so
  * what lands on the page is finished rather than a placeholder that needs the
- * server to mean anything. The reasoning is in TravelElements.tsx, and the
- * short version is that the print renderer must never depend on a fetch.
