feat(urd): mærket bliver ð, og frontend-bygget bliver deterministisk

## Mærket

Urds oplagte mærke var ᚢ uruz — bogstavet navnet begynder med i den ældre
futhark, præcis som Verdandes er ᚹ wunjo. Det blev tegnet sådan først.

Men uruz er allerede et af husets egne produkter, og dets egen
`scripts/gen-icons.ts` siger i sin kommentar at den "draws the Uruz rune (ᚢ)
in rune-gold" med "a tall left vertical, a shoulder across the top, and a
shorter" — altså samme glyf, samme konstruktion, kun en anden farve. To af
samme persons apps side om side på en hjemmeskærm, hvilket er nøjagtig det
sted mærket skal kunne skelnes.

ᚦ thurisaz blev forkastet et niveau nede af samme grund: en stav med en
trekant til højre, og det er ᚹ også. Ved 16px er de én form.

Så bogstavet frem for runen: ð, ethet i Urðr. Centreret ved at tælle malede
pixels frem for ud fra path-tallene, fordi en centreret kasse ikke er en
centreret glyf:

  verdande ᚹ   blæk x  53–108  midte 80.5  ·  y  18–131  midte 74.5
  urd      ð   blæk x  39–110  midte 74.5  ·  y  15–134  midte 74.5

Verdandes +5.5 i x er dens egen bevidste forskydning — en tung stav ved
siden af et let flag skal sidde til højre for midten for at se centreret ud.
ð er symmetrisk nok til at undvære den, og de to er enige i y.

Læsbarhed, målt: ð læses fra 32px og op. Ved 16px er det en klat, og det er
ᚹ også — en favicon er ikke det, der skiller to installerede apps i en dock.

`productRune` hedder nu `productMark`, fordi ð ikke er en rune.

## Determinisme

SvelteKits `kit.version.name` er som standard `Date.now()`. Millisekundet
landede i version.json, i index.html og i service-workeren, ændrede
indholdshashen på hver chunk der refererer dem, og dermed deres filnavne. To
bygninger af samme commit havde forskellige filer i sig.

Dockerfilen har i et år sagt at `-trimpath` og en tom buildid "keep the
output reproducible". Flagene gjorde deres arbejde; frontenden i binæren bar
et tidsstempel. Sætningen var falsk, og ingen læste den.

Fastgjort til VERSION, som udgivelsen allerede sender ind, og `dev` når
intet sætter den. Målt ved at bygge to gange og diffe træet, før og efter.
Prisen er at et lokalt `npm run build` ikke længere ligner en ny version for
service-workeren — hvilket kun betyder noget på en udrullet instans, hvor
udgivelsen sender det rigtige mærkat.

Det gør også CI's nye påstand mulig: de to images deler alle lag, så urd
bærer samme binær som verdande frem for en genbygning der tilfældigvis
matcher.

 mounted, the sidebar has no way to them, search answers with notes only, and the
 program calls itself urd in its tab, its wordmark and its web manifest.
 
+## Running the notes edition
+
+There is one image. The edition is an environment variable on the container:
+
+```
+docker run -e VERDANDE_EDITION=notes -v urd-data:/data -p 8080:8080 \
+    ghcr.io/kristianwind/verdande:latest
+```
+
+No second image and no rune of its own, deliberately.
+
+The edition is for an operator who wants an instance that genuinely has no task
+routes — the routes are absent from the router, not hidden in the interface. It is
+**not** how urd is normally reached. That is being built as a second face of one
+instance, with its own entry point and its own web manifest, so that both can be
+installed as separate apps while sharing one database, one login and one set of
+links. Until that lands, this page describes the edition only.
+
+Two details that surprise people who look inside:
+
+- **The binary is called `/verdande`** and the database file is `verdande.db`, in
+  both editions. Not an oversight: it is the same binary, and renaming the file per
+  edition would be a migration hazard in exchange for nothing a user sees.
+- **The icons for both editions ship in the one image.** The server decides which
+  to serve at `/icon.svg`, because Safari looks for `apple-touch-icon.png` by name
+  and never reads the manifest, so renaming paths would have left iOS with the
+  wrong mark.
+
+## Moving between the two, measured
+
+A `/data` directory moves between the editions in **both directions, losslessly**.
+Same binary, same schema, same migrations — so this is not a feature that was built,
+it is a property that was checked:
+
+| step | result |
+|---|---|
+| verdande creates a notebook, a note in it, and a task | 1 note, 1 task |
+| the same directory, `VERDANDE_EDITION=notes` | `needs_setup: false` — same account. The note keeps its title, its body **and its `project_id`**. `/api/v1/tasks` → 404 |
+| the same directory, back to `full` | the task is still there; so is the note |
+
+The ownership stayed at the panel's service account through all three.
+
+So the way to move notes is to change the variable. `GET /export/notes.zip` is for
+getting notes **into other programs** — it writes one `.md` per note and carries the
+body and nothing else: no notebook, no sharing, no attachments, no pinned flag. That
+is the right division of labour, because the database already holds those.
+
+!!! note "The task rows stay"
+    An instance run as `notes` still has its tasks in the database; they are simply
+    not served. Harmless on a fresh instance, dead weight on a converted one — and
+    worth knowing before handing a converted instance to somebody else.
+

+       as one family — same width, same round caps, same plate.
+
+       NOT a rune, and that is the whole story of this file. The obvious mark was
+       ᚢ uruz, the letter the name begins with in the elder futhark, exactly as
+       Verdande's is ᚹ wunjo. It was drawn that way first. Then: uruz is already
+       one of this author's products, and uruz/scripts/gen-icons.ts says in its own
+       comment that it "draws the Uruz rune (ᚢ) in rune-gold" with "a tall left
+       vertical, a shoulder across the top, and a shorter" one — the same glyph,
+       the same construction, differing only in colour. Two of one person's apps
+       side by side on a home screen, which is precisely where this mark is meant
+       to be distinguishable.
+
+       ᚦ thurisaz was considered next, for the ð itself, and rejected for the same
+       reason one level down: it is a stave with a triangle on its right, and so is
+       ᚹ. At 16px they are one shape.
+
+       So the letter rather than the rune. ð is unmistakably Nordic, nothing else
+       here uses it, and it is a closed bowl where both neighbours are open staves.
+
+       Centred by counting painted pixels — white on black, headless Chromium, the
+       plate removed so the card is not what gets measured — rather than from the
+       path numbers, because a centred box is not a centred glyph:
+
+         verdande ᚹ   ink x  53–108  centre 80.5   ·  y  18–131  centre 74.5
+         urd      ð   ink x  39–110  centre 74.5   ·  y  15–134  centre 74.5
+
+       Verdande's +5.5 in x is its own deliberate nudge: a heavy stave beside a
+       light flag has to sit right of centre for the ink to look centred. ð is
+       symmetric enough not to need it, and the two agree exactly in y.
+
+       Legibility, measured rather than hoped: it reads as ð at 32px and above. At
+       16px it is a blob — and so is ᚹ, and a favicon is not what tells two
+       installed apps apart in a dock. -->
