nesquena-hermes c73f2ff387 v0.50.264 polish followups: i18n parity + assistant-output readability
Closes #1442 (server-side _LOGIN_LOCALE missing ja/pt/ko)
Closes #1443 (promote _isImeEnter helper to 6 other Safari Enter guards)
Closes #1446 (glued-bold-heading lift for LLM thinking-block output)
Closes #1447 (markdown heading visual hierarchy in chat messages)

All four issues were filed by the Opus pre-release advisor on the v0.50.264 batch
or by Cygnus via Discord (relayed by @AvidFuturist, May 1 2026). They share a
common shape — narrow, well-scoped, independent of each other, all adding
regression tests.

== #1442: _LOGIN_LOCALE parity (api/routes.py + static/i18n.js) ==

Added entries for ja/pt/ko to the server-side _LOGIN_LOCALE dict that renders
the localized login page BEFORE the JS i18n bundle loads. With v0.50.264
shipping Japanese as the 8th built-in locale, ja/pt/ko users were seeing the
English login page even with their language preference set.

While auditing static/i18n.js for English leakage, also fixed:
  - ko: 10 user-facing login/sign-out/password keys still in English
  - es: 3 sign-out/auth-disabled keys still in English

Tests: tests/test_login_locale_parity.py (20 tests) — pins both invariants:
  (a) every locale in i18n.js LOCALES has a matching _LOGIN_LOCALE entry
  (b) every locale's login-flow keys (13 of them) are translated, not English

== #1443: window._isImeEnter promotion ==

PR #1441 fixed the Safari IME-composition Enter race in the chat composer
(`#msg`) by widening the guard from `e.isComposing` to a `_isImeEnter(e)`
helper that combines three signals (isComposing || keyCode===229 ||
_imeComposing flag). Six other Enter-input handlers were left on the original
narrow guard and would still drop IME composition Enters on Safari for
Japanese/Chinese/Korean users.

Promoted the helper to `window._isImeEnter` (defined in static/boot.js) and
replaced the `e.isComposing` guards at all six sites:

  - static/sessions.js: session rename, project create, project rename
  - static/ui.js: app dialog (confirm/prompt), message edit, workspace rename

The state-free part of the helper (`isComposing || keyCode===229`) handles
Safari's race for any focused input without needing per-input composition
listeners — only `#msg` keeps the local `_imeComposing` flag.

Tests:
  - tests/test_issue1443_ime_helper_promotion.py (9 tests) — pins each site
    + verifies no raw `e.isComposing` Enter-guards remain in sessions.js/ui.js
  - tests/test_ime_composition.py — alternation regex extended to accept
    the windowed helper form (loosen-test-on-shape-change pattern from
    v0.50.264 reflection notes)

== #1446: glued-bold-heading lift (static/ui.js renderMd + Python mirror) ==

LLMs in thinking/reasoning mode emit "section headers" glued to the end of the
previous paragraph with no whitespace:

    Para 1 text.**Heading to Para 2**

    Para 2 text.**Heading to Para 3**

The renderer correctly produces inline `<strong>` per CommonMark, but it looks
like trailing emphasis on the body text rather than a section break. Cygnus
reported this as "Markdown feedback 2 of 3."

Added a single regex pre-pass in renderMd():

    s.replace(/([.!?])\*\*([^*\n]{1,80})\*\*\n\n/g, '$1\n\n**$2**\n\n')

Constraints chosen to avoid false positives:
  - Trigger only on `[.!?]` IMMEDIATELY before `**` (no space) — almost always
    an LLM-glued heading, not intentional emphasis
  - Inner text ≤80 chars, no `*` or newline (single-line only)
  - Trailing `\n\n` required — preserves "this is **important** to know."
    mid-paragraph emphasis untouched
  - Position: after rawPreStash restore, before fence_stash restore — fenced
    code blocks stay protected (their content is `\x00P` / `\x00F` tokens
    when the lift runs)

Mirrored in tests/test_sprint16.py render_md() so both stay in sync.

Tests: tests/test_issue1446_glued_heading_lift.py (17 tests, 5 of which drive
the actual ui.js renderMd via node) — covers all 3 trigger forms (.!?), all 4
preserve-emphasis cases the issue spec'd, fenced/inline code protection,
chained glued headings, source-level position pin, regex shape pin.

== #1447: markdown heading visual hierarchy (static/style.css) ==

Pre-fix sizes in `.msg-body`:
  h1 18px, h2 16px, h3 14px (= body), h4 13px, h5 12px, h6 11px

So h3 was indistinguishable from body and h4/h5/h6 were SMALLER than body.
Cygnus's report: "Markdown feedback 3 of 3 — Headings seem to be missing
across the board in Hermes. They're there, but all plaintext."

New sizes:
  h1 24px (border-bottom)  h2 20px (border-bottom)  h3 17px  h4 15px
  h5 14px (uppercase, tracked)  h6 13px (uppercase, tracked, muted)

All headings now `font-weight:700` + `color:var(--strong)` for stronger ink.
h5/h6 use uppercase + letter-spacing for "label-style" affordance instead
of being smaller-than-body.

Synced .preview-md (file preview pane) to match exactly so a markdown file
preview and a chat message render identically. Added missing h4/h5/h6 rules
to .preview-md (it only had h1-h3 before).

Updated data-font-size="small"/"large" h1-h6 overrides to scale
proportionally with the new defaults. Hierarchy preserved at all three
font-size settings.

Tests: tests/test_issue1447_heading_hierarchy.py (9 tests) — pins the size
hierarchy, the bottom borders on h1/h2, the uppercase affordance on h5/h6,
the .preview-md sync, and the small/large override scaling.

== Verification ==

  pytest tests/ -q                                  → 3748 passed (+56 new)
  bash ~/WebUI/scripts/run-browser-tests.sh         → 20 + 11 PASS
  bash ~/WebUI/scripts/webui_qa_agent.sh 8789       → 23/23 PASS

Visual confirmation in browser at port 8789:
  - Heading hierarchy clearly visible at all 6 levels
  - Glued-bold lift produces separate paragraphs as designed
  - window._isImeEnter accessible from any module after boot.js
  - Login page renders ja/pt/ko strings correctly (curl -s /login)
