+ * #205: the Scopes tab's sub-tab (Overview / Hop Depth / Regions / Hygiene)
+ * and its 1h/24h/7d window, and the Wardriving tab's window, lived only in
+ * sessionStorage, so a link to e.g. Hop Depth could not be shared. They are
+ * now in the hash next to ?tab=:
+ *
+ *   sub=<overview|hopdepth|regions|hygiene>   Scopes sub-tab
+ *   swin=<1h|24h|7d>                          Scopes window

+ *
+ * (?window= stays the global analytics time picker; it has other values and
+ * drives the shared loads, so the tabs get keys of their own.)
+ *
+ * Contract pinned here:
+ * - a URL value wins over sessionStorage, and is stored for the next plain
+ *   visit of the tab;
+ * - without a URL value the stored value is used and written to the URL;
+ * - an unknown or hostile URL value falls back to the default (never to the
+ *   stored value), never throws and never reaches a selector (#193/#194);
+ * - the default view keeps today's URL (no sub/swin/wdwin);
+ * - clicks write the URL; switching to another tab drops these keys.
+ *
+ * Runs the REAL app.js api(), url-state.js and analytics page in one vm with
+ * a fake fetch and a small fake DOM whose buttons come from the markup the

+ * - #/analytics?tab=scopes&sub=hopdepth opens Hop Depth on a cold load and
+ *   when navigated to from another page;
+ * - clicks write the URL, reload and back/forward restore the view;
+ * - a URL value wins over the sessionStorage one;
+ * - a hostile ?sub= falls back to Overview without a page error;
+ * - the default view keeps the URL it had before (#/analytics?tab=scopes),
+ *   and switching to another tab drops the keys.
