merge: engelske skærmbilleder, og otte steder hvor fladen blev ved med at være dansk

Skærmbillederne er engelske, fjorten i alt, og der er to mennesker i dem. Det
sidste er ikke pynt: halvdelen af det, programmet er til, findes ikke med én
konto — en ansvarlig, et navn i historikken, en medlemsliste, og "Venter på
andre" som andet end en tom side.

Sproget kommer fra kontoens locale og ikke fra strenge skrevet i hånden, hvilket
er dét, der fandt fejlene: otte steder, hvor grænsefladen blev ved med at være
dansk, uanset hvad kontoen sagde. "Forsinket" og "I dag" skrevet ind i markup,
"Uden sektion" som boardets første kolonne, gentagelsesreglerne halvt oversat,
alle nitten navne på hændelser i historikken, og et `da-DK` hårdkodet i Kommende.
Gentagelsesreglerne er flyttet til `when.js`, så menuen og mærket ikke kan blive
uenige igen — det er præcis, hvad den fil er til.

README's billeder havde været brudte siden `37605ba`, som lavede PNG'erne om til
WebP og slettede dem, uden at teksten fulgte med: forsidebilledet og alle seks i
tabellen var 404 på GitHub. Og noterne — hele funktionen — stod ikke nævnt hverken
i README, på forsiden eller i dokumentationen.

Nu skrives PNG til docs og WebP til site, altså præcis dét, de to steder læser.
Før efterlod hver kørsel tolv usporede PNG'er i site, som intet pegede på.

+# Mailboxes
+
+Star a mail and it becomes a task.
+
+This is the other direction from [mail to task](mail.md): instead of forwarding
+something, Verdande reads a mailbox you connect and makes a task out of anything
+you have flagged. Nothing else in the mailbox is touched, and nothing is ever
+sent.
+
+Each mailbox belongs to the person who connected it. Two people on one instance
+connect their own and see only their own — there is no shared inbox and no
+administrator who can read yours.
+
+## Gmail
+
+**Settings → Integrations → Gmail → Connect.**
+
+Gmail needs an OAuth client, which is the instance's registration with Google
+rather than anybody's account — see [Configuration](configuration.md#gmail).
+Once it is set up, each person connects their own mailbox through it.
+
+Choose what makes a task:
+
+| Trigger | What it reads |
+|---|---|
+| Starred | Anything you have starred |
+| Label | Anything carrying a label you name |
+
+!!! note "The app stays Internal if your client is Internal"
+    An OAuth client registered as *Internal* in a Google Workspace can only be
+    used by accounts in that workspace. A personal `@gmail.com` address will be
+    refused with `org_internal`, and that is the client working as configured.
+    Switching to *External* means refresh tokens that expire every seven days
+    until Google has verified the app — for one personal account, forwarding to
+    your [mail-to-task address](mail.md) is the shorter road.
+
+## iCloud, Fastmail and anything else over IMAP
+
+**Settings → Integrations → Mailboxes → Add a mailbox.**
+
+You need three things:
+
+| Field | Example |
+|---|---|
+| IMAP server | `imap.mail.me.com:993` |
+| Username | your address |
+| App password | not your ordinary password — see below |
+
+The connection is tested before it is saved. A mailbox that cannot be read is
+refused while you are still looking at the form, rather than accepted and then
+failing quietly every ten minutes.
+
+Flag a message — the flag, not unread — and it becomes a task on the next sweep.
+Unread is a state you are still using yourself, and a sync that consumed it would
+be taking something away.
+
+### App passwords
+
+Every host worth naming issues a separate password for applications, which you
+can withdraw on its own without changing the one you sign in with. Use that.
+
+- **iCloud** — [appleid.apple.com](https://appleid.apple.com) → Sign-In and
+  Security → App-Specific Passwords
+- **Fastmail** — Settings → Privacy & Security → Integrations → New app password
+
+The password is [encrypted at rest](configuration.md#secrets), and it is never
+returned by the API once saved.
+
+### Office 365 does not work here
+
+Microsoft has closed IMAP to passwords; it wants its own OAuth flow. There is no
+app password that will get you in, and a mailbox pointed at `outlook.office365.com`
+will be refused. Forward to your [mail-to-task address](mail.md) instead.
+
+## How often
+
+Every ten minutes, in the background. **Fetch now** does it immediately, which is
+for when you have just connected something and want to see it work.
+
+A run reads at most twenty-five messages, so a mailbox with years of flagged mail
+in it fills up over several sweeps rather than in one.
+
+## Disconnecting
+
+**Disconnect** on the mailbox. The tasks it made stay — they are your work now,
+not the mailbox's. Nothing is read after that, and the stored credential is
+deleted rather than merely disabled.

+## A password

+What the first account is created with. Nothing is emailed, nothing is registered
+anywhere: the first person to open a fresh instance creates the administrator
+account, and after that people arrive by invite link.
+
+## A code on top of it
+
+**Settings → Account → Two-factor.** An ordinary TOTP secret — any authenticator
+app reads the QR code. Once it is on, the password alone is not enough.
+
+Recovery codes are shown once, when you turn it on. They are the way back if the
+phone is gone, and they are not shown again.
+
+## A passkey
+
+**Settings → Account → Passkeys → Add a passkey.**
+
+A key on a device instead of a secret in your head. The private half never leaves
+the device — a phone's secure element, a laptop's keychain, a hardware key — and
+the signature is bound to the address it was made for, so a convincing copy of the
+sign-in page at a different address gets nothing.
+
+Give each one a name you will recognise later. *min bærbare* is what makes a list
+of keys reviewable, and a list nobody can read is a list nobody revokes from.
+
+Passkeys need the address in `VERDANDE_BASE_URL` to be a hostname. Browsers refuse
+to make one for a bare IP address, so an instance reached at `http://192.168.1.10:8080`
+will show the passkey section as unavailable rather than failing at the moment
+somebody tries.
+
+!!! note "One is enough, two is better"
+    Lose the only device holding your only passkey and you are back to the
+    password. Keep the password, or register a second key — a phone as well as a

+// Package beacon answers one question for the project, and refuses to answer any
+// other: how many installations are out there.
+//
+// It sends two values once a day — an anonymous id the installation made up for
+// itself, and the version it is running — and nothing else. No IP is stored by
+// the collector, no hostname, no domain, no account, no usage. The payload is
+// small enough to be printed in full on the settings page, and it is, because a
+// promise about telemetry is worth exactly as much as the reader's ability to
+// check it.
+//
+// # On by default, and off in one click
+//
+// The alternative that was asked for first was mandatory, and the argument
+// against it is practical rather than principled: it cannot be enforced. The
+// domain can be blocked, the binary can be patched, and a fork removes it in its
+// first commit — so mandatory buys nothing over on-by-default, while costing the
+// trust the rest of this program works for. Secrets are sealed here, the key is
+// kept out of the database, and the backup page warns you what a copy contains.
+// Telemetry you are not allowed to refuse is the one sentence in that story that
+// does not fit.
+//
+// So: on by default, said plainly, one switch to turn it off. That collects
+// essentially the same number and leaves nobody feeling tricked.
+//
+// # Where this disagrees with the rest of the program
+//
+// `config.UpdateCheck` is off unless asked for, and its comment gives the reason:
+// "a self-hosted app that reaches out without being told to has broken the deal
+// its operator made by self-hosting." That is the same situation as this one, and
+// the two defaults do not agree.
+//
+// The disagreement is written down here rather than smoothed over, because it is
+// a real one and the reader deserves to see both halves. The case for treating
+// them differently is that the update check reveals an instance to a third party
+// (GitHub) and returns something the operator can act on, while this returns
+// nothing and goes to the project itself — and that a count nobody sends is a
+// count that does not exist, whereas an update nobody checks for is one you can
+// still go and look up. Whether that is a distinction or an excuse is a judgement
+// call, and it was made deliberately by the person whose instance this is.
+//
+// If it is ever decided the other way, the change is one word: the default in
+// `beaconSettings`. Nothing else in this package assumes which way it points.
+//
+// # What the collector can still see
+//
+// A request has a source address whether or not anybody writes it down. The
+// collector does not store or log it, and the code is arranged so that it never
+// reaches a function that could — but it passes through a reverse proxy and a
+// tunnel on the way, and those keep their own logs. Saying "we send no IP" would
+// be a half-truth; what is true is that nothing here records one.

+"""Apple Noter → Markdown, med formateringen i behold.
+
+Den første udgave af det her brugte `textutil -convert txt`, som er hurtigt at
+skrive og smider alt væk: overskrifter, fed, monospace, lister. Ti prøvenoter
+viste hvad det koster — en note er ikke kun sine ord, den er også hvordan de er
+sat op, og et referat med overskrifter er ikke det samme referat som en klump.
+
+Apple Noter er HTML indeni, og HTML kan læses. Kortet er lille, fordi Noter selv
+bruger et lille sæt:
+
+    <h1> <h2> <h3>   overskrifter        →  # ## ###
+    <b> <i> <u>      fremhævning         →  ** * <u>
+    <tt>             monospace           →  ```-blok
+    <ul><li>         punktliste          →  -
+    <ol><li>         nummereret          →  1.
+    <div>            en linje            →  linjeskift
+    <br>             en tom linje        →  tom linje
+
+Kører på din egen maskine og sender ingenting nogen steder.
