Kgothatso Ngako 1f24aaf4bb fix: give the two single-field screens their initial focus, and check 200% text on a device
Phase 3, final step, of docs/material-design-conformance.md. The tree had **zero** uses of
`FocusRequester`, `LocalFocusManager` or `focusProperties`, so no screen defined where
keyboard focus starts.

**Two places get it, and only two.** M3's flow guidance asks for an initial focus per
screen and, for a dialog, that "focus is set to the dialog component, likely to a specific
interactive element within the dialog such as a text input field":

  - `StartDirectMessageToNpubOrNip05Dialog` -- one field and two buttons. Without this the
    dialog opens with nothing focused, so a keyboard or switch user tabs in from wherever
    focus happened to be.
  - The desktop `PassphraseGate` -- the first screen of the desktop app, whose entire
    content is one field, and where there is no tap to give it focus. Somebody who opens
    the app and starts typing should not have to reach for the mouse first.

The other seven text-field screens deliberately do **not** auto-focus. Requesting focus
raises the software keyboard, and on a screen that leads with content somebody wants to
read -- AddArtifact's chapter list, WriteNewNote's reply preview -- that covers the thing
they came for. M3 asks for the initial focus to be *defined*, not for a field to be
grabbed; on those screens the definition is "the top of the content".

**Large text verified on a device rather than reasoned about.** Two passes:

A static one first, since the failure mode is a fixed height around text. All 23 fixed
vertical dimensions outside `Spacer`s are icons, images and progress indicators -- 12 to
40dp `.size()` calls, a 200dp image, a 180dp `heightIn` cap. Nothing wraps text in a fixed
box.

Then at `font_scale 2.0` on an API 36 emulator, three screens: onboarding, the message
list, and a chat room. All reflow without clipping. The chat room is the useful one --
system messages wrap to two lines and their timestamps and chevrons stay aligned, the
composer keeps its full width, and the transcript stays readable. `font_scale` was put
back to 1.0 afterwards.

The physical device attached to this machine was left alone. `font_scale` is a
system-wide setting and changing it on somebody's actual phone to test an app is not a
reasonable thing to do; a fresh emulator was booted for it instead.

**An unrelated flaky test, measured and left alone.** `ChronicleApplyJvmTest > an answered
catch-up leaves one line, whatever it took to deliver` failed once during this commit's
verification with

    expected:<[chronicleRequested, chronicleReceived]> but was:<[chronicleReceived, chronicleRequested]>

and reproduces at **1 failure in 8** consecutive `--rerun` invocations on this tree. Both
transcript lines are written within the same second and the DAO's ordering has no
documented tie-break, so either order can come back. That is chronicle and database code;
nothing in this branch touches it. Whether it is a test bug or a real one -- two lines
swapping places in a user's transcript on reload would be a defect -- wants deciding by
somebody in that code, so it is filed rather than patched here.

**Tests.** 944 pass, 595 jvm over 72 classes and 349 android over 44, unchanged. Focus and
window insets are properties of a running composition; there is no Compose UI test
infrastructure here, and a test asserting the modifier is present would restate the diff.

mantra docs

Notes on the parts of this app whose behaviour is not recoverable by reading the code alone — where the reasoning lives in a protocol, a failure mode that is silent, or a decision that looked arbitrary and was not.

document covers
shared-key-ceremony.md ChillDKG over NIP-17: the rounds, the approval gates, the chat transcript, participant ordering
shared-key-derivation.md deriving further keys from the group's threshold key with FROST tweaks — why not BIP32, why no chain code, and the one rule that must not be broken
frost-batch-signing.md signing several events in one ceremony — why one nonce can never cover two messages, and the phased schema, wire and UI work that follows from it
marmot-membership.md how members join an MLS group, and the epoch race that makes a missing member look like a successful invite
member-chronicle.md handing a member added after the work was done the group's signed record — why the events are not on the wire at all, and why the room's id is enough to verify them
marmot-direct-messages.md a one-to-one message inside a group as a stock NIP-59 gift wrap — what its MIP-03 carve-out costs, why the sender cannot read their own, and the one query that would broadcast it
mls-skipped-keys.md why a group event that arrives a moment late is dropped for good, which flows trigger it, the quartz fix, and the partial mitigation in this app
long-running-sync.md the chat subscriptions that stay open instead of pulling once per screen — why the request queue could not simply hold one, and how the group filter follows the room list
dead-code.md code in the sync and relay stack that nothing calls, why each piece is still there, and which of it is a bug rather than a leftover
jvm-target.md what desktop support cost, phased — why the native chain was already done, why an empty source set in our phoenix fork was the real blocker, and why DAO tests need none of it
material-design-conformance.md what the M3 foundations actually require, measured against all 43 screens — the colour pairing that renders the app's own proposals invisible, and eight phases that put the decisions back in the theme

Start with the ceremony if you are new to this area; the Marmot notes all assume it. Read the skipped-keys note before debugging any "the other device never got it" report — it is silent, and it looks like every other kind of delivery failure. The sync note stands alone, and the dead-code inventory reads as a follow-up to it. The batch-signing note is a phased plan that has been built: read it after the derivation note, whose one rule is the same one it is built around. The member chronicle note is a phased plan that has not been built, and reads as the membership note's unanswered half: what a member who joins late can be given, and the one thing they cannot. The jvm-target note is unrelated to all of them: it is a build and packaging story. The Material Design note is a phased plan that has not been built, and is the only one about what the app looks like rather than what it does; read the jvm-target note first if you want to know why its adaptive-layout phase exists.
