V1.8.0: the fallen are hidden, and allies can revive the dead

- A dead character, or a monster or NPC at 0 HP, is out of the fight: the
  server no longer sends it to players, target marks included, and it has
  no turn. Healing or reviving brings it straight back.
- The DM's screen leaves the fallen out too until "Show dead" is ticked,
  which lists them in a group of their own, marked hidden.
- Players see dead characters by name in a Fallen box. The player whose
  character is on turn in a battle gets "Try revive" there if that
  character is on their feet and knows a spell that revives, at a level
  they can cast. The dead come back at 1 HP.
- Spells have a "Revives" tick in the campaign's spell list. Revivify and
  Raise Dead have it, in the library and in existing campaigns.
- A dead character cannot be added to an encounter until revived.
- All packages at version 1.8.0.

+|---|---|---|

+| Stable | At 0 HP, no longer rolling | Healing wakes them; damage makes them Dying again |

+
+**Rolling.** While Dying, type what the d20 showed and click **Death save**.

+|---|---|
+| 1 | Two failures |
+| 2 to 9 | One failure |
+| 10 to 19 | One success |
+| 20 | Back up with 1 HP, tallies cleared |
+
+- **Three successes:** Stable. The tallies are cleared.
+- **Three failures:** Dead.
+- **Stabilise** makes a Dying character Stable without a roll, for when
+  someone steadies them (a Medicine check, a healer's kit, a spell).
+- **Damage at 0 HP** is one failed save, and makes a Stable character Dying
+  again. Damage soaked entirely by temp HP does not count. The app cannot tell
+  a critical hit; the DM adds its second failure by clicking a pip.
+- **Massive damage:** if a blow leaves as much as the character's max HP
+  still to take once HP reaches 0, they are Dead at once. A character with
+  12 max HP on 5 HP dies from 17 damage or more.
+- **Healing** from 0, by any amount, puts the character back up and clears
+  the tallies and Stable.
+- **Dead** characters cannot be healed: Heal is refused with a message. The
+  DM clicks **Revive at 1 HP**, then heals as normal. In a battle, an ally
+  with a reviving spell can do the same on their own turn, and until then the

+- **The DM's screen leaves it out as well**, until the DM ticks **Show dead**

+  there are any). Ticked, they are listed in a group of their own at the
+  bottom, "Out of the fight, hidden from players", each with a "Hidden from
+  players" badge, and everything on the card still works. The tick is not
+  remembered: it is off again when the page is reopened.
+- **It has no turn.** Next Turn, Next Round and Begin Battle pass over it.
+- It stays in the encounter: nothing is removed, and gold is still split with
+  a dead character.
+
+It is worked out from hit points each time, not stored, so it undoes itself:
+heal a monster or NPC above 0, or revive a character, and they are back on
+everyone's screen and back in the turn order.
+
+**Reviving a dead character.** Players see dead characters by name only, in a
+**☠ Fallen** box above the list. There are two ways back:
+
+- The **DM** ticks Show dead and clicks **Revive at 1 HP** on the dead
+  character's card (or does it on the sheet), at any time.
+- An **ally** tries it: in a battle in progress, the player whose character is

+  if that character is capable. Capable means on their feet (above 0 HP) and
+  knowing a spell that is ticked **Revives** in the campaign's spell list
+  ([SPELLS.md](SPELLS.md)), at a level they can cast. The library's Revivify
+  (level 3) and Raise Dead (level 5) are ticked already.

+  fight, and is not shown a mark the DM leaves on one.
+- The combatant **on turn** cannot be marked: nobody targets themselves, and
+  their card has no Target button until the turn passes. To heal or hurt them
+  on their own turn, use the buttons on their card.
+- A target's card is outlined in red for everyone and reads "Targeted by
+  <whoever is on turn>".
+- While anyone is marked the DM gets an **attack bar** above the list, which
+  stays in view while scrolling. It shows who is attacking whom, each target's
+  AC and HP, and the attacker's attacks: a character's equipped weapons (all
+  of them if none are equipped) and damaging spells, or a monster's or NPC's
+  attack and damage. The amount box is ready to type in; **Damage** (or
+  Enter) and **Heal** change HP exactly as the buttons on a card do.
+- Targets stay marked after damage, for a second attack. They are cleared
+  when the turn or round moves on, when the encounter begins, ends or is
+  reopened; a target that is removed from the encounter is unmarked.
+
+**Area attacks**
+
+An attack on several targets is harder to land and its damage is shared.
+
+- **Harder to hit.** Every target's AC counts as higher for each target
+  beyond the first, by the campaign's **area attack AC penalty**. The DM sets
+  it in the campaign settings, from 0 (no penalty) to 10; it starts at 2, which
+  gives:
+
+  | Targets | Added to each AC |
+  |---|---|
+  | 1 | 0 |
+  | 2 | +2 |
+  | 3 | +4 |
+  | 4 | +6 |
+
+  The attack bar shows the AC to beat with the penalty already added
+  ("17 (15 +2)"), and each target's card says "area attack, AC +2".
+- **Who was hit.** Each target has a tick box, ticked to begin with. Untick
+  anyone the roll missed; they take nothing.
+- **Sharing the amount.** Type the total. "Split between those hit" (the
+  default) shares it evenly, any remainder going one point each to the first
+  targets marked: 7 between three is 3, 2 and 2. "Full amount to each" gives
+  every target hit the whole amount. Each target's share is shown before it
+  is applied.
+- A target with no hit points to track is left out of the sharing.
+
+The app does not roll the attack or decide whether it hits: the DM compares
+the roll with the AC shown and types the damage.
