Define and implement the panel's empty and error states

Close the DESIGN-HANDOFF open question "empty and error states are
unspecified" with a written addendum (design/PANEL-EMPTY-STATES.md)
and its implementation in both panel cards:

- quest log resolves one state in priority order: no adventurer in
  the path, integration not set up, records unreachable
  (unavailable/unknown), away via direct navigation, all-clear
  zero-quest day, all-done fallback before the 1c takeover, then the
  normal three-window columns
- party board renders a notice instead of an empty grid when no
  children are configured or every child's sensors are unresolvable,
  and muted "Unknown" plates for partially unresolvable children
- a shared notice panel (panel tokens, role=status) replaces every
  state that would otherwise render a blank parchment; frames,
  kicker and dock always stay

+## Automation Blueprints
+
+NestQuest ships four automation blueprints in
+`custom_components/nestquest/blueprints/automation/`. Import them in
+Home Assistant under **Settings → Automations & Scenes → Blueprints**
+(or place the files in your `config/blueprints/automation/` folder),
+then create one automation per blueprint, filling the inputs with your
+household's choices.
+
+### Wiring to the integration's notification settings
+
+The integration's options flow records your notification choices —
+notify target, morning/afternoon/end-of-day times, and a toggle per
+automation. The blueprints take their own inputs at import time;
+fill them from the same values you stored in the options flow (the
+integration does not push its settings into imported automations):
+
+| Blueprint input | Options-flow counterpart |
+|---|---|
+| `morning_time` (default 08:00) | `morning_summary_time` |
+| `afternoon_time` (default 15:00) | `afternoon_reminder_time` |
+| `report_time` (default 20:00) | `end_of_day_report_time` |
+| `send_summary` / `send_reminder` / `send_report` / `celebrate` | the four `*_enabled` toggles |
+| `notify_target` | `notify_target` (your notify service, e.g. `notify.mobile_app_your_phone`) |
+
+The end-of-day report deliberately runs BEFORE the midnight missed
+sweep and reads the same day's data — do not schedule it at the
+day-rollover time.
+
+### The four blueprints
+
+1. **Morning summary** (`morning_summary.yaml`) — at the configured
+   time, lists every child whose `binary_sensor.nestquest_<child>_present_today`
+   is on and what they owe from `sensor.nestquest_<child>_quests_remaining_today`.
+   Children not present today are omitted entirely.
+
+2. **Afternoon reminder** (`afternoon_reminder.yaml`) — at the
+   configured time, notifies only about present children who still
+   have open quests. Sends nothing at all when every present child is
+   clear.
+
+3. **End-of-day report** (`end_of_day_report.yaml`) — one message per
+   evening: each present child's completion count and the quests they
+   still owe (the ones the midnight sweep will mark
+   `nestquest_quest_missed`). Absent children are omitted. Sends
+   nothing on an all-clear day unless `send_even_when_clear` is on.
+
+4. **Day-complete celebration** (`day_complete_celebration.yaml`) —
+   triggers on the `nestquest_child_day_complete` event (which only
+   fires when quests were owed and all are complete, so a zero-quest
+   day never celebrates). Create one `input_text` helper
+   (`nestquest_last_celebrated`) for the dedupe: the automation
+   records each celebrated child as `<child_id>:<today>` and
+   celebrates each child at most once per day — a re-cleared day does
+   not re-fire, but a second child clearing the same day still
+   celebrates.
+
+### Example package
+
+```yaml
+# One automation per blueprint — Settings → Automations & Scenes →
+# Create → Blueprint, then pick each NestQuest blueprint.
+#
+# morning_summary:   morning_time 08:00, notify_target notify.mobile_app_your_phone
+# afternoon_reminder: afternoon_time 15:00, same notify target
+# end_of_day_report:  report_time 20:00, send_even_when_clear false, same target
+# day_complete_celebration: input_text.nestquest_last_celebrated,
+#                            celebration_message "Legendary! {{ trigger.event.data.child_name }} cleared every quest today!"
+#
+# Every blueprint has its own send/celebrate toggle input; turn an
+# automation off entirely from HA's automation menu.
+```
+
+### Events the automations rely on
+
+| Event | Payload |
+|---|---|
+| `nestquest_quest_completed` | child_id, child_name, instance_id, quest_title, window, due_date, due_time, occurred_at (UTC ISO-8601), was_on_time |
+| `nestquest_quest_uncompleted` | child_id, child_name, instance_id, quest_title, window, due_date, due_time, occurred_at |
+| `nestquest_child_day_complete` | child_id, child_name, quests_due, quests_completed, occurred_at |
+| `nestquest_quest_missed` | child_id, child_name, instance_id, quest_title, window, due_date, due_time, occurred_at (fired by the nightly sweep) |
+
+Sensors the automations read: `sensor.nestquest_<child>_quests_due_today`
+(attributes: `child_id`, `child_name`, `present`, `instances`,
+`admin_instances`), `..._quests_remaining_today`,
+`..._quests_completed_today`, and
+`binary_sensor.nestquest_<child>_present_today`.

+# Panel empty & error states — design addendum
+
+Closes the gap DESIGN-HANDOFF.md lists under "Open questions": *"Empty and error
+states are unspecified by request (child with no quests, everyone away, integration
+unconfigured, DB unreachable). Panel must not render a blank parchment — decide
+before shipping the card."*
+
+All decisions below reuse PANEL-SPEC.md's approved aesthetic — parchment ground,
+double frame, dock, panel tokens, no text below 22px, no alpha-muted ink — and add
+one shared component per card: a **notice panel** (radius 20px, `--nq-p-card-panel`,
+2px `--nq-p-panel-border`, `--nq-p-panel-shadow`, centred icon + headline + body).
+The frame, wordmark row, kicker and dock always render; only the content area
+changes. **No state renders a blank parchment.**
+
+## 1. What the data can say
+
+The cards read `sensor.nestquest_<child>_quests_due_today` (plus siblings). One of
+four things comes back, and the card must tell them apart:
+
+| Backend condition | What the card sees | Card's interpretation |
+|---|---|---|
+| Resolving (DB fine) | numeric state + attributes (`child_name`, `present`, `instances`) | normal, all states below |
+| Integration not configured | entity does not exist at all | **not set up** |
+| Backend unreachable (DB locked, refresh failed) | state `unavailable` | **records unreachable** |
+| Child deactivated / absent from snapshot | state `unknown` | **records unreachable** (same panel voice: the records do not answer) |
+
+An away child (presence `present: false`, from the due-sensor attributes with the
+presence binary sensor as fallback) is *not* an error: it is a first-class panel
+state ("On travels"). Away children get no instances (materialiser skips them), so
+away is detected from the presence flag, never from a zero quest count.
+
+## 2. Quest log — state priority
+
+`nestquest-quest-log-card` resolves exactly one state, in this order:
+
+1. **No adventurer in the path** (direct navigation to a URL with no child slug —
+   misconfigured `board_path`/`quest_log_path`) → notice *"No adventurer chosen"*,
+   body *"Open The Party and tap your crest to open your quest log."*
+2. **Not set up** (entity missing) → notice *"NestQuest is not set up yet"*, body
+   *"A parent needs to finish setting up NestQuest."*
+3. **Records unreachable** (`unavailable`/`unknown`) → notice *"The records cannot
+   be reached"*, body *"The party's records are quiet right now. NestQuest will
+   return shortly."*
+4. **Away** (present flag false) → away notice: dashed muted panel (the away-plate
+   gradient), tent icon, *"<Name> is on travels"*, *"The quest log unlocks when
+   they return."* and, when `next_present` is known, *"Returns <weekday>, <Mon D>"*.
+   Direct navigation is the one path that can reach this state (the board's away
+   plate is not tappable); the log answers it honestly instead of showing an empty
+   column set. Header renders with the crest in away colours and the sub line
+   `… · On travels`; the remaining-count block is hidden (it is meaningless while
+   away).
+5. **No quests today** (present, due = 0) → all-clear notice, sun icon, *"No quests
+   today"*, body *"Nothing was posted for today, <Name>. Enjoy the day's rest!"* —
+   never three bare empty columns. The header and remaining block stay (0 quests
+   left, party progress), so the log still reads like the log.
+6. **All quests done** (due > 0, remaining = 0) → the fallback celebration that
+   shows until the 1c quest-complete screen takes over: centred wax-seal mark (the
+   `--nq-p-seal` tokens at 78px, check glyph, −6°) with headline *"Quest complete"*
+   — the same phrase screen 1c uses — and body *"Every quest is claimed, <Name>.
+   The seal is set for today. Returning to The Party shortly."* The idle return
+   (§3.5) is what actually navigates back; 1c remains the designed takeover.
+7. **Normal** → the three-window column layout of PANEL-SPEC §3.1 unchanged. A
+   window with no quests still renders its head alone, exactly as the spec says.
+
+Notices sit in the columns' content area, vertically centred. Error notices (states
+1–3) replace the header entirely — there is no honest name to headline when the
+records do not answer — while states 4–6 keep the full header.
+
+## 3. Party board — state priority
+
+`nestquest-party-board-card` resolves per configured child, then at board level:
+
+1. **No children configured** (`child_order` empty) → board notice *"NestQuest is
+   not set up yet"*, body *"A parent needs to finish setting up NestQuest before
+   the party can gather."*
+2. **Every configured child unresolvable** → one board notice instead of a grid of
+   broken plates: *"NestQuest is not set up yet"* when the entities are missing,
+   *"The records cannot be reached"* when they answer `unavailable`/`unknown`.
+3. **Partial** (some children resolve, some do not) → the board still renders the
+   resolving plates; an unresolvable child renders a muted, dashed plate in the
+   away geometry with a compass icon and the pill label **"Unknown"**, progress
+   line `—`, empty bar, **not tappable**. It must not claim "Home today" (0 of 0)
+   and must not lie "On travels": the records simply do not say.
+4. **Normal** → the plates grid of PANEL-SPEC §2 unchanged (present + away plates).
+
+The hint line ("Tap your crest…") is hidden in board-level notice states — there
+is nothing to tap.
+
+## 4. Shared rules
+
+- **Never a blank parchment.** Every render path emits the frames, wordmark,
+  kicker, dock, and either content or a notice panel. The dock already degrades to
+  date + time when weather is unset (PANEL-SPEC §2.3); that behaviour is unchanged.
+- **Notice panel type scale:** icon 46px, headline 40px/700 Cinzel
+  (`--nq-p-font-heading`, `--nq-p-ink`), body 24px/600 Nunito
+  (`--nq-p-ink-secondary`), `role="status"` so assistive tech announces it.
+- **Tone.** The panel speaks tabletop (PANEL-SPEC vocabulary) but never lies: an
+  error says the records cannot be reached, not that everything is fine. Error
+  copy names the actor who can fix it (a parent) or promises the return of the
+  data — no stack traces, no entity IDs.
+- **No interaction in error/away states.** No confirm dialog, no idle return
+  changes, no navigation attempts. Notices are static.
+- Both cards implement the same resolution rules, so the board and the log never
+  disagree about whether the integration is up.

+"""Tests for the NestQuest day-complete celebration automation blueprint.
+
+The celebration fires on the ``nestquest_child_day_complete`` event —
+which NestQuest only fires when quests were owed and all are complete,
+so a zero-quest day can never celebrate.  Dedupe design (per-child,
+per-day): the household points ONE ``input_text`` helper at the
+blueprint; the condition celebrates only when THIS child has no
+``<child_id>:<today>`` entry stored, and the action rewrites the
+helper with only today's entries plus the new one — so a child who
+un-completes and re-completes the same day is celebrated once, not
+twice, while a second child clearing the same day is still celebrated.
+
+The harness (YAML ``!input`` loader, state fixtures, jinja rendering)
+is shared in :mod:`tests.blueprint_helpers`; the directory-wide shape
+and entity-discipline tests in test_blueprints.py cover this file
+too.  ``now()`` in the dedupe condition is injected by the test as a

+"""Tests for the NestQuest end-of-day report automation blueprint.
+
+The end-of-day report closes the day for the parent: every PRESENT
+child gets a completion line (so the parent always receives the day's
+summary when the report runs), children who still owe quests get their
+open count called out on that line, and absent children are omitted
+entirely.  The report runs deliberately before the midnight
+missed-quest sweep so it reads the same day's data, and by default an
+all-clear day sends nothing — unless the household opts into
+send-even-when-clear.  The harness (YAML ``!input`` loader, state
+fixtures, jinja rendering) is shared in
+:mod:`tests.blueprint_helpers`; the directory-wide shape and
+entity-discipline tests in test_blueprints.py cover this file too.
