jubnl 59c2624fa9 docs(wiki): explain the three currencies and how they relate
Trip currency, expense currency and display currency answer three different
questions, and nothing said so: the trip currency wasn't documented at all (it
had no picker until now), and Budget-Tracking conflated the other two while
still claiming 47 currencies and a display currency that always came from
Settings.

Add a Currencies page as the one place they're defined together — the trip
currency as the accounting base, the expense currency as the receipt with its
rate frozen at entry, the display currency as presentation-only — plus what
happens when a trip's currency changes, which currency a public share renders
in, and what belongs to the Costs addon versus the trip itself.

Rewrite Budget-Tracking's currency section against it, document the currency
field in Creating-a-Trip and the display currency in Display-Settings (which
never mentioned it), and note the sharer-or-trip fallback in Public-Share-Links.

# Creating a Trip
<!-- TODO: screenshot: trip creation form with date and cover fields -->
![Trip creation dialog](assets/TripCreate.png)
## Opening the Dialog
Click the **New Trip** button in the dashboard toolbar (or the **Create First Trip** button on the empty state) to open the Create Trip dialog.
You can also open it directly via a deep link: navigate to `/dashboard?create=1`. This is the URL used by system notices that prompt you to create a trip.
## Fields
### Title (required)
The trip name. Cannot be empty — saving is blocked until a title is entered.
### Description (optional)
A short free-text description shown on the trip card.
### Dates
Set a **Start date** and **End date** using the date picker. The day count is calculated automatically when both are set.
If you leave **both** dates empty, a separate **Day count** field appears. Enter a number between **1 and 365** to create a date-less itinerary with a fixed number of days.
You cannot set only one date and leave the other blank via normal interaction — setting a start date auto-fills or adjusts the end date to preserve the previous duration.
### Currency
The trip's currency — its **accounting base**. Every expense in the Costs tab is converted into it, and every balance and settle-up suggestion is calculated in it. Defaults to **EUR**; 165 currencies are available.
Pick the currency you will actually settle up in. It is not a cosmetic label, but it is not a one-way door either: you can change it later from the same dialog (with the `trip_edit` permission), and TREK re-bases the existing expenses so no money moves — see [Currencies → Changing the trip currency](Currencies#changing-the-trip-currency).
> This is **not** the same as the display currency in Settings → Display, which only changes what *you* read. See [Currencies](Currencies).
### Cover Image
The cover image is displayed on the trip card and as the background of the Spotlight card. You can add one in three ways:
- **Drag and drop** an image file onto the dashed upload area.
- **Paste from clipboard** — if you have an image in your clipboard, paste it anywhere in the dialog.
- **File picker** — click the upload area to browse for a file.
- **Search Unsplash** — type a query to pick a stock photo. If this returns *"Unsplash search unavailable"* (common on VPS/datacenter IPs), configure a free Unsplash Access Key — see [Environment-Variables → Image Search (Unsplash)](Environment-Variables#image-search-unsplash).
When **creating** a new trip the cover image field is always visible. When **editing** an existing trip it is only shown if you have the `trip_cover_upload` permission. For a new trip, the image is uploaded immediately after the trip is created.
### Reminder
A push notification sent before the trip departs. The field shows a set of preset options:
| Option | Days before departure |
|---|---|
| None | 0 |
| 1 day | 1 |
| 3 days | 3 |
| 9 days | 9 |
| Custom | 1–30 (you enter the number) |
When **creating** a new trip the reminder field is always visible. When **editing** an existing trip it is only shown to the **trip owner** or **admin** users.
If reminders are disabled on your instance (`trip_reminders_enabled = false`), the reminder section is shown at reduced opacity with an informational message in place of the preset buttons.
> **Admin:** Trip reminders are controlled by a server-side feature flag (`trip_reminders_enabled`). Contact your administrator to enable them.
### Members
Add initial trip members from the members selector. On a **new** trip, selected members are queued locally and added to the trip immediately after it is saved. The selector shows all registered users on your instance except yourself.
## Saving
Click **Create Trip**. The trip is saved and you are taken to the [Trip-Planner-Overview](Trip-Planner-Overview) for the new trip.
