/* ─── (was) RESERVE VEHICLE — now shared modal + timeline styling ─────────
   The Reserve Vehicle page was retired (vehicles.html/vehicles.js deleted),
   but this file must NOT be deleted with it. Alongside the now-unused
   .reserve-* / .vtl-* rules it carries selectors other pages rely on:

     .modal-header/.modal-body/.modal-card/.modal-close  index.html,
                                                         epn-network.html, app.js
     .dow-label, .today-header, .weekend                 app.js,
                                                         transfer-calendar.js
     .w3, .org                                           crew.html, heatmap.js

   Removing the genuinely dead rules is safe but fiddly, and was deliberately
   not attempted when the page was retired — the shared rules were verified by
   grepping every selector here against the remaining HTML/JS.
