// Info booklet — a fullscreen page over the lobby (2026-10-05), in the Difficulty page's and Map select's look: the books, their
// pages and the entries down the left, the entry chosen on the right. Inter, solid strips with a left rule, the gold accent.
//
// ⛔ CLASS NAMES THE LOBBY DOESN'T USE (`bk…`). This page renders INSIDE the lobby's root, so every `.lobby .x` rule in
// LobbyMenu.razor.scss reaches an element of ours called `.x` (MapBrowser.razor.scss's first note, learnt the hard way).
//
// ⚠️ `pointer-events: all`, because the lobby's root is `none`: a panel that declares neither cannot be clicked in s&box.
//
// ⚠️ SIZES IN THE 1080-HIGH UI SPACE, like the lobby's, Map select's and the Difficulty page's.
