docs: name every approval-screen amount string, fix stale zero claim (closes #369)

The README's amount-display section claimed a genuine zero always renders
`0.0000`. That is corrected and scoped: it holds for the ERC-20 amount and for
the swap's `Amount` line on a literal-zero `amountIn` in a V2/V3 exact-in swap
or a zero `WRAP_ETH`. Only two zeros are stated in words before the floor — the
swap's `Min. received` (any zero minimum) and its V4 exact-in `Amount` (an
`amountIn` of zero, V4's open delta).

A new list names every string an amount slot can show: a formatted quantity,
`Unlimited`, `All available (V4 open delta)`, `None (no minimum guaranteed)`,
base units with decimals unknown, and `Unknown (not named in the calldata)`. It
also records that a zero `minBalance` on a `BALANCE_CHECK_ERC20` step now reads
the no-minimum wording where it once read `0.0000`. Each claim checked against
the tree. Docs only.

 # Completed Steps
 
+- 2026-09-21: The network fee a transaction can commit is bounded by the product
+  of the gas limit and the fee per gas, not by each field alone, and the
+  wallet's own send is bounded the same way
+  ([#399](https://git.eeqj.de/sneak/AutistMask/issues/399)). The two per-field
+  ceilings in `src/shared/approvalVerify.js` were checked independently, so a
+  gas limit and a fee that were each under their own ceiling still multiplied to
+  thousands of ETH — a fee a gas-consuming contract really collects — while the
+  comment claimed the ceiling caught exactly that. `assertWithinCeilings` now
+  also refuses a transaction whose gas limit times its fee per gas
+  (`maxFeePerGas` for a type-2 transaction, `gasPrice` for a legacy or type-1
+  one) exceeds `MAX_TOTAL_FEE`, a new constant of 1 ETH beside the existing
+  ceilings, so both callers — where the dApp transaction is populated and where
+  the signed artifact is verified — reject it with a full sentence naming the
+  fee and the limit. The wallet's own send in `src/popup/views/confirmTx.js`
+  pinned no fee fields, so ethers filled them from whatever the configured node
+  answered with nothing bounding them; it now populates the transaction and runs
+  the same check before signing, showing the same error in the confirmation
+  screen's reserved errors box so nothing on screen moves. Deliberately out of
+  scope: comparing a supplied fee against the node's own suggested fee, which
+  the absolute bound already makes unnecessary for the balance-draining case. 1
+  ETH is a plain constant, one line to change; the owner may prefer another
+  figure.
+- 2026-09-21: The test recovery phrase no longer survives in a release bundle,
+  and the committed-key guard matches by content
+  ([#351](https://git.eeqj.de/sneak/AutistMask/issues/351)). `DEBUG_MNEMONIC` in
+  `src/shared/constants.js` is now behind the `__BUILD_DEBUG__` define, so a
+  release build folds the phrase to `null` and no emitted bundle carries it; it
+  used to survive as dead text because `module.exports` keeps the const alive.
+  `script/verify-build` now fails a release build if the phrase appears in any
+  emitted file, so the fold cannot silently regress. `tests/extensionId.test.js`
+  scans the content of every tracked file for a PEM private-key header instead
+  of matching filename extensions alone.
+- 2026-09-21: A transaction response is honoured only for a transaction
+  approval, and the three remaining approval-settlement paths are pinned
+  ([#262](https://git.eeqj.de/sneak/AutistMask/issues/262)). The liveness fix
+  the issue asks for — settle `4001` on release when the window it would be
+  retried in is gone — already landed with
+  [#271](https://git.eeqj.de/sneak/AutistMask/issues/271); this closes the rest.
+  `AUTISTMASK_TX_RESPONSE` now refuses any approval that is not a transaction
+  approval, so a reject no longer retires a sign or connection approval and a
+  signed artifact never runs the broadcast path against one, which before only
+  failed closed by throwing deeper in. Tests pin the site-connection port's
+  approve, reject and disconnect paths against a transaction approval
+  broadcasting behind them: each is declined and the dApp still receives its
+  broadcast result.
+- 2026-09-21: `docs/RELEASE.md`, linked from `README.md`, states the release
+  procedure as a numbered list a newcomer can follow: confirm `main` is green in
+  CI, confirm the one version in the three files matches the intended tag,
+  `make package` from a clean checkout, verify `SHA256SUMS`, tag `vX.Y.Z`, then
+  distribute per browser. Each step names who performs it (owner-only steps
+  marked) and the check that it worked. The distribution step is written as
+  pending the owner's choice on
+  [#386](https://git.eeqj.de/sneak/AutistMask/issues/386), with the Firefox and
+  Chrome options named but none settled. Docs only
+  ([#387](https://git.eeqj.de/sneak/AutistMask/issues/387)).
+
+- 2026-09-21: Adding a second wallet no longer accepts a different password with
+  nothing saying it is a separate one
+  ([#374](https://git.eeqj.de/sneak/AutistMask/issues/374)). Each wallet has its
+  own encrypted secret, so per-wallet passwords are by design; the add-wallet
+  screen said only "Choose a password". A note now appears on that screen when
+  the profile already holds a wallet, stating that each wallet has its own
+  password and this one need not match any already in use. It is shown only
+  then, since the first wallet has no other password to differ from, and it
+  stays consistent with the no-reset reality of
+  [#312](https://git.eeqj.de/sneak/AutistMask/issues/312) by promising no
+  recovery or reset.
+
+- 2026-09-21: The dApp approval and transaction-status screens resolve a token's
+  symbol from the bundled list, then the tokens the user tracks, then the block
+  explorer's report — the same sources and precedence the amount line already
+  used for the token's scale
+  ([#323](https://git.eeqj.de/sneak/AutistMask/issues/323), folding in
+  [#354](https://git.eeqj.de/sneak/AutistMask/issues/354)). A token the user
+  added by hand, or holds a balance of, is now named rather than labelled
+  `Unknown token`, and a non-bundled ERC-20 is no longer carried onto the wait
+  screen as `ETH`. A tracked or explorer-reported name stays subject to the
+  spoof rule, so resolving a symbol is not a new way to wear a known ticker.
+- 2026-09-21: The debug/testnet banner no longer shows the internal view id to
+  the user in a release build
+  ([#375](https://git.eeqj.de/sneak/AutistMask/issues/375)). The banner appended
+  the active view's id (e.g. `[TESTNET] (approve-tx)`), which is developer
+  vocabulary sitting directly above the approval screen's carefully worded
+  authorization text. The suffix is now gated on the compile-time `DEBUG`
+  constant rather than `isDebug()`, so it survives only in a debug build; a
+  testnet or the runtime debug toggle still raises the banner but without the
+  view id.
+
+- 2026-09-21: The Confirm Delete button on the delete-wallet screen no longer
+  stays dead after a successful delete
+  ([#335](https://git.eeqj.de/sneak/AutistMask/issues/335)). The password route
+  disabled the button before the decrypt and never re-enabled it, so a second
+  delete in the same popup session needed a reopen; the lost-password route
+  re-enabled its own button in its leave hook, so the two screens behaved
+  differently. Both now reset through the shared `finishDelete()`, the one path
+  both routes take, so they behave the same and the button is live for the next
+  delete.
+
+- 2026-09-21: `README.md` now documents the approval screen's amount-slot
+  vocabulary and no longer contradicts itself
+  ([#369](https://git.eeqj.de/sneak/AutistMask/issues/369)). The stale claim
+  that a genuine zero still renders `0.0000` is corrected: it holds for the
+  ERC-20 amount, and also for the swap's `Amount` line on a literal-zero
+  `amountIn` in a V2/V3 exact-in swap or a zero `WRAP_ETH`. Only two zeros are
+  stated in words upstream — the swap's `Min. received` (any zero minimum) and
+  its V4 exact-in `Amount` (an `amountIn` of zero, V4's open delta). The
+  amount-display section now names every string a slot can show — a formatted
+  quantity, `Unlimited`, `All available (V4 open delta)`,
+  `None (no minimum guaranteed)`, base units with decimals unknown, and
+  `Unknown (not named in the calldata)` — and records that a zero `minBalance`
+  on a `BALANCE_CHECK_ERC20` step now reads `None (no minimum guaranteed)` where
+  it once read `0.0000`. Docs only; each claim checked against the tree.
+
+- 2026-08-30: An address no longer wraps, or is shortened to fit, in any of the
+  common views ([#380](https://git.eeqj.de/sneak/AutistMask/issues/380)). The
+  wallet list was the reported case: the address shared one row with the
+  `[info]` and `[x]` controls and folded onto a second line, which turns one
+  42-character string the user is meant to compare into two shorter ones — the
+  shape an address-poisoning attack wants. The fix is layout, not CSS: every
+  address in the popup now sits alone on a full-width row, with the colour dot,
+  the wallet title, the ENS name and the explorer link moved onto a strip above
+  it, and the transaction rows carry the counterparty's whole address instead of
+  a `truncateMiddle()`d one squeezed in beside the amount. `truncateMiddle()`
+  keeps its 10-character cap and its 32-character floor moved into
+  `renderAddressHtml()`, so the guarantee outlives having no callers. The e2e
+  suite measures every rendered address in a real Chromium — whole, one line
+  box, inside its row and inside the popup — across Home, the address, token,
+  receive, send and transaction detail screens, the confirmation screen and the
+  dApp transaction prompt.

+# Releasing AutistMask
+
+This is the procedure that turns a green `main` into a tagged, packaged release.
+It gathers into one place what is otherwise spread across the `Makefile` and
+three `README.md` sections, so the person cutting a release does not have to
+reconstruct the order from them.
+
+There is one version, declared in three files (`package.json`,
+`manifest/chrome.json`, `manifest/firefox.json`), and `make package` builds and
+packages but publishes nothing. `make build` and `make package` can be run by
+anyone; tagging, signing, packing a CRX and any upload need credentials only the
+owner ([@sneak](https://sneak.berlin)) holds and are marked **owner-only**
+below. Releases are tagged from `main` (see the Workflow section of `TODO.md`),
+so the "release commit" throughout is the `main` commit the milestone PR merged.
+
+## Procedure
+
+1. **Confirm `main` is green in CI.** The `check` workflow
+   (`.gitea/workflows/check.yml`) runs `script/cibuild`, i.e. `docker build .`,
+   and the `Dockerfile` runs `make check` as a build step, so a green `check`
+   run is a green `make check`. Find the run for the exact release commit on the
+   tracker's Actions view. _Check:_ that commit's `check` run succeeded; running
+   `make check` on a clean checkout of the commit reproduces it and exits 0.
+
+2. **Confirm the version matches the intended tag.** `package.json`,
+   `manifest/chrome.json` and `manifest/firefox.json` must all declare the same
+   `X.Y.Z`. `make build` fails when they disagree, but nothing checks that they
+   equal the tag you mean to create — that is this manual step. _Check:_ all
+   three files read the same `X.Y.Z`, and it is the version you intend to tag
+   `vX.Y.Z`.
+
+3. **Build and package from a clean checkout of that commit.** From a fresh
+   clone, or a working tree with no local modifications (`git status` clean),
+   checked out at the release commit: run `make setup`, then `make package`.
+   `make package` runs `make build` first, so the archives can only be made from
+   a `dist/` verified against that build's own receipt as a release (not debug)
+   build. It writes three files into `release/`:
+   `autistmask-chrome-<version>.zip`, `autistmask-firefox-<version>.xpi`, and
+   `SHA256SUMS`. _Check:_ those three files exist and `<version>` in the archive
+   names is the version confirmed in step 2. The Firefox `.xpi` is **unsigned**
+   (see step 6 and "Installing on Firefox" in `README.md`).
+
+4. **Verify `SHA256SUMS`.** The archives are deterministic — sorted entries,
+   fixed timestamps, fixed compression — so a second `make package` from another
+   clean checkout of the same commit produces byte-identical files. Verify the
+   recorded digests against the files with `sha256sum -c SHA256SUMS`, run from
+   `release/`. To confirm reproducibility, run `make package` again on a
+   separate clean checkout and compare the digests. _Check:_ `sha256sum -c`
+   reports `OK` for every file, and an independent build's digests match.
+
+5. **Tag the release commit.** _(owner-only)_ Create an annotated tag `vX.Y.Z`
+   on the release commit and push it: `git tag -a vX.Y.Z` (with a message), then
+   `git push origin vX.Y.Z`. _Check:_ `git tag` lists `vX.Y.Z`, and
+   `git rev-parse vX.Y.Z^{commit}` resolves to the release commit.
+
+6. **Distribute per browser.** _(owner-only; pending the owner's choice on
+   https://git.eeqj.de/sneak/AutistMask/issues/386)_ How 1.0.0 is distributed on
+   each browser is not yet decided; it is the open question on that issue, and
+   the concrete steps cannot be written until the owner records a choice there.
+   These steps need credentials only the owner holds. The options under
+   consideration are:
+    - **Firefox** — the packaged `.xpi` is unsigned, and release Firefox and ESR
+      refuse an unsigned add-on:
+        - (a) AMO self-distribution signing (unlisted): submit the `.xpi` to AMO
+          with the owner's credentials; AMO returns a signed `.xpi` installable
+          on every Firefox, with nothing listed publicly.
+        - (b) AMO listed: as (a), plus a public AMO listing and review.
+        - (c) Ship the unsigned `.xpi` and state that Firefox support means
+          Developer Edition, Nightly, or an Unbranded build with
+          `xpinstall.signatures.required` set to `false`.
+    - **Chrome** — the repo packs no CRX and publishes nothing; the extension id
+      is fixed by the `key` in `manifest/chrome.json`:
+        - (a) Chrome Web Store (unlisted): upload the `.zip` with the owner's
+          developer account; the store delivers installs and updates.
+        - (b) Self-hosted CRX signed with the private key the owner holds
+          (`chrome --pack-extension=dist/chrome --pack-extension-key=<path to the .pem>`),
+          installable only via enterprise policy on Windows and macOS, so
+          realistically Linux-only.
