While attached it follows the\n * route cursor (route_cursor_core.js): with no index it shows UNLIT \u2014 the\n * wheel with nothing lit, a dash on each line, the clear button disabled \u2014\n * and with one it shows that segment's wheel and words (2026-10-18: it\n * sits under the profile now, the route sheet's HALF state on a phone,\n * rather than in the route title's place). Every surface that places a point\n * already writes the cursor: a tap on the route's line (map.js) and a tap\n * on the profile (route_rail.js). Nothing here is placement.\n *\n * The per-route arrays \u2014 each segment's path and gradient \u2014 are worked out\n * once on attach, so a cursor move is one lookup and one redraw. All the\n * arithmetic and the words are route_point_card_core.js's; all the copy is\n * the partial's strings template.\n *\n * CLEARING THE POINT is a press on the wheel (2026-10-02): the wheel sits\n * in a button (`[data-route-point-card-clear]`) that sets the cursor's\n * index to null, which takes this header back to unlit.\n * Escape does the same (route_rail.js). The panel's \u00D7 closes the route.\n *\n * Depends on i18n_strings.js, route_slope_core.js, aspect_wheel_core.js\n * and route_point_card_core.js, loaded before it.\n *\n * Publishes (frozen `window.pwaRoutePointCard`):\n *\n *   attach({cursor, slope, coordinates, profile, sampleCount})\n *              \u2014 follow one route's cursor, showing the header for a point\n *   detach()   \u2014 stop following and show the header unlit\n *   element    \u2014 the header itself\n */\n\n(function routePointCardInit() {\n  'use strict';\n\n  var card = document.getElementById('route-point-card');\n  if (!card) return;\n\n  /** The wheel's size in the header, CSS px: the mockup's. */\n  var WHEEL_SIZE = 48;\n\n  // Server-translated copy; the literals are the English fallback (see\n  // static/js/i18n_strings.js).\n  var STRINGS = self.pwaStrings.read('route-point-card-strings-template', {\n    label: \"Skier's track: %(headline)s; Terrain slope: %(ground)s\",\n    join: '%(before)s \u00B7 %(after)s',\n    'label-join': '%(before)s, %(after)s',\n    'compass-0': 'N',\n    'compass-1': 'NE',\n    'compass-2': 'E',\n    'compass-3': 'SE',\n    'compass-4': 'S',\n    'compass-5': 'SW',\n    'compass-6': 'W',\n    'compass-7': 'NW',\n    'heading-pair': '%(first)s \u2192 %(second)s',\n    'label-heading-pair': '%(first)s to %(second)s',\n    'kind-ascent': 'Ascent',\n    'kind-descent': 'Descent',\n    'kind-traverse': 'Traverse',\n    'kind-fall-line': 'Fall line',\n    'headline-level': 'Level',\n    'headline-no-height': 'No height data',\n    'with-band': '%(text)s \u00B7 %(band)s',\n    'label-with-band': '%(text)s, %(band)s',\n    'band-under': 'under %(high)s\u00B0',\n    'band-range': '%(low)s\u2013%(high)s\u00B0',\n    'band-over': '%(low)s\u00B0+',\n    'label-band-under': 'under %(high)s degrees',\n    'label-band-range': '%(low)s to %(high)s degrees',\n    'label-band-over': '%(low)s degrees or more',\n    'ground-flat': 'Flat',\n    'ground-moderate': 'Moderate',\n    'ground-steep': 'Steep',\n    'ground-very-steep': 'Very steep',\n    'ground-extremely-steep': 'Extremely steep',\n    empty: '\u2013',\n    'ground-unknown': 'No terrain data',\n    'ground-falling-left': \"%(ground)s, falling skier's left\",\n    'ground-falling-right': \"%(ground)s, falling skier's right\",\n    'ground-falling-left-then-right': \"%(ground)s, falling skier's left, then right\",\n    'ground-falling-right-then-left': \"%(ground)s, falling skier's right, then left\",\n  });\n\n  var wheelEl = card.querySelector('[data-route-point-card-wheel]');\n  var clearEl = card.querySelector('[data-route-point-card-clear]');\n  var headlineEl = card.querySelector('[data-route-point-card-headline]');\n  var groundEl = card.querySelector('[data-route-point-card-ground]');\n\n  /** The open route's cursor, or null while detached. */\n  var cursor = null;\n  /** Removes the header's subscription to `cursor`. */\n  var unsubscribe = null;\n  /** The open route's arrays, worked out once on attach. */\n  var route = null;\n\n  /**\n   * Draw the wheel into the header.\n   *\n   * @param {*} state The wheel's state.\n   * @param {string} label Its accessible name.\n   */\n  function drawWheel(state, label) {\n    var wheel = self.pwaAspectWheelCore;\n    if (!wheel || !wheelEl) return;\n    wheelEl.innerHTML = wheel.aspectWheelSvg({ size: WHEEL_SIZE, state: state, label: label });\n  }\n\n  /**\n   * The wheel with nothing lit: no heading, flat ground, no gradient.
