/* Left navigation drawer — the phone's navigation surface.
 *
 * The topbar spreads navigation across three surfaces: the primary tab strip,
 * the goal-period selector, and the Sidebar panel menu. All three fit a desktop
 * header; on a phone they wrap onto three rows and eat a fifth of the screen.
 * The drawer is those three surfaces as one list behind one button, and
 * mobile.css hides the surfaces it replaces.
 *
 * On a desktop the drawer is not reachable, and that is deliberate: its
 * hamburger would sit next to the my-calendars hamburger — two identical icons,
 * two different panels, one corner. The desktop already shows the tab strip,
 * the goal-period selector and the Views dropdown, so nothing is lost. Only
 * `.mobile-nav-drawer-toggle`'s `display` is breakpoint-dependent; see its rule
 * at the bottom of this file.
 *
 * This file is NOT inside a media query, which is why it is not in mobile.css:
 * everything there lives inside one by contract, and a phone-only stylesheet
 * can express "shown on a phone" but not "closed until asked for". The phone
 * *differences* — hiding the topbar surfaces the drawer replaces, and showing
 * the toggle — stay in mobile.css.
 *
 * Load order: after layout.css/components.css (so the doubled
 * `.nav-icon-button.mobile-nav-drawer-toggle` selector below is not needed to
 * win a tie, though it is kept for clarity) and before mobile.css.

/* The hamburger — PHONE ONLY. Hidden here and un-hidden by the one rule in
   mobile.css's media query, which also hides `.my-calendars-toggle` there. That
   pairing is the whole point: exactly one three-line icon in `.topbar-left` at
   any width. On a desktop it is the my-calendars button (it opens the calendar
   list beside the view); on a phone it is this one (my calendars becomes a
   drawer row). Showing this at every width — which it did until 2026-07-29 —
   puts two adjacent identical icons that open different things in the top-left
   corner.

   Layout properties stay unconditional so the phone rule only has to say
   `display`. Doubled selector because `.nav-icon-button` in components.css is
   also a single class — see the matching note in layout.css. */
