v0.1.0

Highlights

• Initial release: switchboard-alerts-card (list, acknowledge, and
  snooze alerts) and switchboard-silence-tile (one person's silence
  status and controls).
• Config is validated up front — a bad option shows a clear Lovelace
  error naming it instead of a card that crashes.
• Accessible by default: focus-trapped dialogs, icon-plus-text state
  (never colour alone), and disabled actions that stay focusable and
  explain themselves.
• Visual editors with English, French, and Spanish translations, with a
  graceful fallback to native alert.* actions where a Notify
  Switchboard service isn't available yet.

Added

• switchboard-alerts-card: lists alert.* entities with acknowledge,
  un-acknowledge, and (when the router supports it) snooze actions. Compact
  badge mode with a dialog, full inline list mode.
• switchboard-silence-tile: shows one person's silence state, active
  snooze count, and last notification, with silence / clear-snoozes /
  lift-silence controls.
• Full setConfig validation on both cards: entities, snooze_minutes,
  mode, target_map, show_acknowledged, person and wake_time are
  checked up front, so a bad config produces a Lovelace error card naming
  the option instead of a card that throws during render.
• unavailable / unknown alerts are a distinct fourth state — a neutral
  chip with text and a mdi:help-circle-outline icon, no actions, and its
  own count on the compact badge. They are never shown as acknowledged.
• Compact badge count chips pair an icon and an aria-label with the
  number: state is never conveyed by colour alone.
• The badge dialog traps focus (Tab / Shift+Tab cycle inside it) and
  Escape closes it and restores focus to the badge button.
• Optional person on the alerts card, passed to
  notify_switchboard.snooze. Without it the menu says the snooze applies
  to everyone.
• "Today" footer on the alerts card, reading
  sensor.switchboard_dropped_today and event.switchboard_delivery when
  those entities exist.
• Clicking an alert's name opens Home Assistant's more-info dialog.
• getGridOptions() on both cards for the sections layout.
• Visual editors built on ha-form with entity/select/object selectors and
  translated labels, degrading to a YAML hint when the Home Assistant
  frontend globals are absent. Emitted configs never carry empty keys.
• English, French, and Spanish translations, selected from
  hass.locale.language.
• Version banner logged on load.
• Graceful degradation: every action that depends on a Notify Switchboard
  0.2.0 service checks hass.services first and falls back to native
  alert.* actions, or marks itself aria-disabled with a visible
  explanation.

Fixed

• "Clear" no longer invents notify_switchboard.silence(minutes: 0), a
  call that is not in the router contract. Clearing snoozes calls
  unsnooze; lifting a silence calls the dedicated unsilence service.
• sensor.<person>_active_snoozes in unavailable / unknown is reported
  as unknown ("—") instead of being read through Number() and shown as
  "No active snoozes".
• "Until wake" is computed on the Home Assistant instance's timezone
  (hass.config.time_zone) rather than the browser's.
• Cards only re-render when an entity they actually read changes, instead
  of on every state change in the instance; the 30 s duration tick is
  skipped when nothing is listed.
• The snooze menu's <summary> keeps its native role and exposes
  aria-expanded; Escape closes it and restores focus.
• Disabled tile actions stay focusable (aria-disabled) and the tile
  explains why in one visible line.
• The dialog scrim uses --dialog-scrim-color, hover text uses
  --text-primary-color, and the host no longer paints its own background
  over the theme's ha-card.
