feat(notes): man kan se hvad man skriver

Formatering vises, mens man skriver. Overskrifter, fed, kursiv, kode, citater,
punkter, #tags og [[links]].

Et spejl bag et gennemsigtigt tekstfelt — samme greb som hurtig tilføjelse bruger
til at vise, hvad parseren forstod. En contenteditable ville lade teksten style
direkte og ville også ødelægge fortryd, autokorrektur og IME. Det er en dårlig
byttehandel i det ene sted i programmet, hvor nogen skriver en halv time i træk.

Mærkerne bliver stående, dæmpede. Obsidian skjuler dem uden for den linje,
markøren står i; at dæmpe dem altid er en mindre idé, der ikke flytter tekst under
markøren mens den bevæger sig — og den overlever mødet med et tekstfelt.

Overskrifter skifter vægt og farve, aldrig størrelse: en større skrift ville fylde
flere linjer end tekstfeltet gør, og så skred alt nedenunder.

Hele risikoen ved grebet er, at de to lag skal flugte tegn for tegn. Prøven måler
det frem for at stole på det: skrifttype, linjehøjde, ombrydning, polstring og den
faktiske højde af de to lag med samme tekst i.

Undervejs: kursiv-passet slugte " og " efter et fed-udtryk, fordi den løse stjerne
stadig var synlig for det. Hvert pas læser nu en kopi, hvor de tidligere pas'
tegn er blændet ud.

+# 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.
