* ci(performance): give the initial-bytes ratchet slack and a labelled override
The exact renderer.initialBytes counter failed PRs for reasons outside
their diff: two concurrent merges left master 108 bytes over the baseline
for hours, and bundler identifier renaming moves the counter by hundreds of
bytes. PRs growing it by 243 and 302 bytes had no way to pass at all,
because the direction check refuses any raised baseline.
- Counter entries accept `slack` (integer, entry unit): the ratchet enforces
`value + slack`, reports how much slack a measurement uses, and still
prints the tighten hint below `value`. renderer.initialBytes gets 4096
bytes, so growth can accumulate at most 4 KiB past the last lowered
baseline while regressions such as +35 KB still fail.
- check-baseline-direction.mjs compares `value + slack`, treats widened
slack like a widened tolerance, and takes `--allow-increase`, which
reports weakened entries as ALLOWED instead of failing.
- CI passes `--allow-increase` only when the pull request (or, for a master
push, the pull request merged as the pushed commit) carries the
perf-baseline-increase label, read from the API so a job re-run picks up
a label added later.
This change widens the slack itself, so its own PR needs the label.

* fix(performance): report slack usage only for entries that have slack
A wall-clock measurement above `value` but within `value × toleranceRatio`
fell into the slack branch and was reported as using "slack", conflating
timing tolerance with counter slack. Only entries with `slack` report it now.

* fix(performance): scope the push-time label and refuse raised counter values
- A master push compares the whole push, but the label was read from the
head commit's PR only, so one labelled PR could cover another commit's
increase in the same push. The label now counts only when the push added
exactly one first-parent commit (a squash or merge of one PR); any other
push that weakens a baseline fails.
- Raising a counter's `value` while narrowing its `slack` lowered the
enforced limit and was reported as "lowered". A counter's value is the
measured evidence and only moves down, so that raise is now a weakening
that needs the label.

* fix(performance): treat a counter/wall-clock type switch as a weakening
Turning `{ value: 100, slack: 10 }` into `{ value: 105, toleranceRatio: 1 }`
skipped the raised-counter-value rule and was reported as a lowered limit.
Switching an entry between counter and wall-clock now needs the
perf-baseline-increase label.

* ci(performance): paginate the label lookups of the direction check
The labels endpoint returns 30 entries per page by default, so a PR with
more labels could miss perf-baseline-increase. Both lookups now request
100 per page and paginate, like the release-note gate.

* perf(web): keep backup/restore and portal helpers off the initial path
#1601 (parental lock) put about 35 KB onto the renderer's initial path by
design (the lock service, lock store and enforcement gate the workspace
resolver and the catalog data sources) and was merged with the ratchet red:
renderer.initialBytes 1,655,428 against the 1,619,993 baseline.
Offset it without touching the lock gate. Code splitting puts a module in the
chunk shared by every entry that reaches it, so helpers only lazy routes use
landed in initial chunks because eager files reach them through barrels:
- PlaylistBackupService (only the lazy settings page) moves to
@iptvnator/services/playlist-backup and out of the services barrel.
- The eager Xtream data layer and root shell import the portal logger and DI
tokens through @iptvnator/portal/shared/util/logger and /tokens instead of
the barrel, whose navigation, keyboard-shortcut and download helpers
(about 45 KB) belong to the lazy portal routes.
renderer.initialBytes 1,655,428 -> 1,598,232 bytes (-57,196).

* perf(web): keep lazy-only services and SafePipe out of main.js
The eager shell imported barrels that re-export Angular injectables and a
pipe it never uses, and their static definitions keep those modules in
main.js: PlaylistFileImportService came with PlaylistContextFacade,
normalizeDateLocale with SafePipe, and the workspace-shell-util barrel with
SettingsContextService, which #1714 grew with match counts. That growth put
master 108 bytes over the renderer.initialBytes baseline #1712 had measured
on a branch without #1714.
Add file-level entries for the three modules and use them from the eager
and settings code: renderer.initialBytes 1,626,127 -> 1,619,993 bytes.

The root shell imported WindowControlsComponent and DialogService through the @iptvnator/ui/components barrel, and esbuild keeps every Angular component module a barrel re-exports, so channel lists, EPG views, @angular/forms, date-fns and the whole Stalker data layer sat in main.js. The shell now uses file-level entries, the Stalker connection editor is a lazy proxy, and the release-notes and external-player info dialogs load on demand with a handled failure path.
renderer.initialBytes 2,714,336 -> 1,626,019 bytes (-40%); the baseline is lowered to the ubuntu ratchet measurement and the production/PWA initial budgets drop to 1.8/2 MB. J1: did-finish-load about -16 ms, first card within noise.

Plan thread C1, journey **J1 `launch`**, counter **`renderer.initialBytes`**. Stacked on #1694 → #1693 → #1692; merge in order.
`apps/web/src/app/app-date-locales.ts` imported the locale data of all 18 supported languages eagerly, so every user shipped and parsed all of it at startup. Each locale is now a dynamic import keyed by the Angular locale id that `normalizeDateLocale()` derives from the app language (`by` → `be`, `ary` → `ar-MA`, `zhtw` → `zh-Hant`); English needs no data.
Ordering is preserved so no template renders a locale whose data has not arrived (Angular throws in that case):
- `main.ts` awaits the initial language's data (from `getInitialLanguage()`) before `bootstrapApplication`.
- Both `TranslateService.use()` call sites, `AppComponent.initSettings()` and `SettingsFormFacade.applySavedSettings()`, register the data first through the new `AppDateLocaleService`.
- A failed load never leaves the locale without data: English formatting is registered under the requested id (eager 1.1 KB `@angular/common/locales/en`), so `DatePipe` renders instead of throwing; the locale is not marked registered, so the next call retries and a success replaces the fallback (review follow-up).
- `AppDateLocaleService.use()` orders switches by request, not by completion: a switch whose data arrives after a newer request is dropped, so the language chosen last wins (review follow-up).
No kill switch: behavior is identical once the locale resolves, and the only new failure mode (a same-origin chunk failing to load) is shared with every lazy route.

Third step of the performance-journeys ratchet, stacked on #1693 (which is stacked on #1692; merge in order, GitHub retargets each to `master`).
- New `Initial bytes ratchet` job in `.github/workflows/ci.yml` (ubuntu-latest): install, `pnpm nx build web --skip-nx-cache` (production configuration, the one users download), then `pnpm run perf:initial-bytes:check`. The job fails when `renderer.initialBytes` exceeds `tools/performance/journey-baselines.json`.
- `dist/performance/` is uploaded as the `performance-journey-summary` artifact on every run, so a failing or tightenable run carries its evidence.
- After review: the job first runs the new `tools/performance/check-baseline-direction.mjs`, which compares `journey-baselines.json` with the revision the change is measured against (the target branch of a pull request, `github.event.before` for a `master` push, `master` for a manual dispatch) and fails on any raised enforced limit (`value × toleranceRatio`), any widened or newly added tolerance, or any removed entry, so a PR cannot grow the payload and raise the baseline to match (lowered limits and new entries pass; a target branch without the file has nothing to weaken). Node tests cover it.
- Docs: the performance-journeys contract and the validation map name the job, and the contract now states that this runner is the canonical measurer (take baseline values from its output, not from a local build).

Second step of the performance-journeys ratchet, stacked on #1692 (merge that first; this PR retargets to `master` automatically).
- `tools/performance/journey-baselines.json`: J1 `launch` / `renderer.initialBytes` = **2,739,510 bytes**, the ubuntu runner's production build of `apps/web` at this content (after #1692 stopped bundling `package.json` into `main.js`). A local macOS build of this pre-#1695 code is 2 bytes smaller in `main.js` (the eager locale imports); once #1695 removes them the two are byte-identical. Correction to an earlier version of this description: the "556-byte macOS vs Linux difference" was almost entirely `package.json` text embedded in `main.js`, which moved with every script edit in this stack, plus this 2-byte residue. The runner is the canonical measurer; the CI run on the stacked #1694 branch (this content plus the job) is where the number is confirmed.
- `tools/performance/check-journey-ratchet.mjs` compares a journey summary with the baselines: a counter above its value fails (exact, no slack), wall-clock entries fail above `value × toleranceRatio`, a baseline without a measurement fails so dropping a measurement cannot disable the ratchet, values below baseline print a "tighten" hint, and measured counters without a baseline are noted only. After review: checking nothing (empty file, or `--only` naming a missing entry) fails; a counter is read only from `counters` and a wall-clock entry only from `wallClock`; the repeatable `--only <journey>/<counter>` flag scopes a check.
- Root scripts: `perf:initial-bytes:check` (measures into its own `dist/performance/initial-bytes.summary.json`, then checks `--only launch/renderer.initialBytes`) and `perf:ratchet:check` (full check); `perf:tools:test` runs both test files, as does `pnpm nx test performance-tools`.
- `docs/architecture/performance-journeys.md` gains the Ratchet section (file format, rules, "baselines only move down"); the validation map lists the check.
The CI job that runs the check on every PR is #1694; C1 (lazy Angular date locales, #1695) then lowers the baseline with the measured output as evidence.
Note: `ci.yml` only triggers on pull requests targeting `master`, so this stacked PR shows no Actions runs until #1692 merges. The evidence runs above were dispatched with `gh workflow run ci.yml --ref <branch>`.

First step of the performance-journeys ratchet (plan thread: J1 `launch`, counter `renderer.initialBytes`).
- `tools/performance/measure-initial-bytes.mjs` reads the built `dist/apps/web/index.html` and sums `index.html` plus every same-origin `<script src>`, `<link rel="stylesheet">` and `<link rel="modulepreload">` it references. Manifest, icons, external URLs and lazy chunks are not counted. A referenced file missing from the build fails the measurement instead of counting as zero bytes.
- `--json` prints the breakdown; `--summary <file>` writes the `journeys.<journey>.counters` shape a ratchet checker will consume (next PR).
- New Nx project `performance-tools` (test + lint targets), Tier B in `tools/coverage/coverage-policy.json`, root scripts `perf:initial-bytes` and `perf:tools:test`.
- New contract `docs/architecture/performance-journeys.md`, linked from the validation map, the agent context map and the README.
- **Review follow-ups:** resources are deduplicated by request URL (query kept, fragment dropped); `index.html` is parsed with parse5 (already a repository dependency, scripting enabled), so comments, bogus comments, raw-text bodies (script/style/noscript/title/textarea), inert `<template>` contents and character references in attributes all follow the HTML5 algorithm instead of a hand-written scanner; the review's edge cases stay as regression tests; docs show the `pnpm --silent` form for JSON output and explain how the counter relates to Angular's rounded "Initial total".
- **Found while measuring:** the environment files and the playback diagnostic panel imported the whole `package.json` (`import packageJson from '@package'`), which esbuild cannot tree-shake, so `main.js` carried the complete file and the counter moved with every script or dependency edit. They now import `{ version }` only (eb662c485): `main.js` shrinks by **11,539 bytes** and the counter no longer depends on `package.json`. Jest's ESM loader exposes JSON only as a default export, so the two web Jest configs map `@package` to a stub that serves the real file's fields as named exports. Release note: `.changes/web-version-only-from-package-json.md` (`type: perf`).
Production build after this PR measures **2,739,508 bytes** (11 files + `index.html`); Angular's "Initial total" is this minus `index.html` and `assets/app-config.js`. The baseline file and the CI check land in the follow-up PRs; C1 (lazy Angular date locales) then lowers it.
