+      summary: The account's standing alarm on tasks that have a clock.
+      description: |
+        Reminders have always had to be set one at a time: a task written as
+        "i morgen kl 9" got a time and no alarm, because nothing creates a reminder
+        by itself. That is the right default for a task with no clock — there is no
+        moment to ring at — and an errand you walk every time for a task with one.
+
+        `minutes` is relative to the due moment and **negative for before it**, the
+        same convention `reminders.offset_min` uses because that is the column the
+        value ends up in: the store adds it to the due time. `0` is exactly at the
+        due moment. `null` turns the default off, which is where every account
+        starts — switching it on for everybody in a migration would have meant
+        alarms nobody asked for, on tasks already lying there.
+
+        A positive number is refused. An alarm after the thing it is warning about
+        is not a reminder, and accepting one here would make the single mistake this
+        value can make — a sign the wrong way round — look like a choice.
+
+        The default never stacks on an alarm the task already has, and a task can
+        opt out as it is written with "ingen alarm" in the quick-add line.

+-- Alarm som standard på opgaver med et klokkeslæt.
+--
+-- Påmindelser har virket længe og skulle sættes én ad gangen: en opgave med
+-- "i morgen kl 9" fik en tid og ingen alarm, for intet skaber en påmindelse af sig
+-- selv. Det er den rigtige standard for en opgave UDEN klokkeslæt — der er intet
+-- tidspunkt at ringe på — men for en med et er det en omvej, man går hver gang.
+--
+-- Minutter i forhold til forfaldstiden, og NULL betyder slået fra. Én nullable
+-- kolonne frem for et flueben plus et tal, så tilstanden "slået til uden
+-- forskydning" ikke findes og derfor ikke kan blive uenig med sig selv.
+--
+-- Fortegnet er det samme som i reminders.offset_min, fordi det er den kolonne,
+-- værdien ender i: lageret LÆGGER tallet til forfaldstiden, så en alarm FØR er
+-- negativ og 0 er præcis på tidspunktet. To forskellige fortegnsregler for det
+-- samme begreb er den slags forskel, der kun viser sig som en alarm, der ringer
+-- på det forkerte tidspunkt.
+--
+-- NULL for alle, der findes i dag, og det er med vilje. At slå den til i en
+-- migrering ville give hver eksisterende bruger alarmer, de ikke har bedt om, på
+-- opgaver de har liggende — og det her er software, andre selv driver. En
+-- indstilling, man selv slår til, er en anden sag end en notifikation, der
+-- pludselig kommer.
