Closes #1529

Problem

On a Vietnamese page, spec groups read 1. Màn hình (Display) and 2. Phần cứng & Hiệu năng (Hardware). The site is multilingual, so each locale should show only its own label.

Change

Spec group headings (product page and compare):

• Each locale shows its own label only:
  • vi: Màn hình, Phần cứng & Hiệu năng, … Pháp lý, Chứng nhận & SAR, and Mạng di động for a watch. Mạng di động and Công nghệ sạc also move to sentence case.
  • en: Display & panel, Hardware & performance, …
  • cs is unchanged, apart from the number.
• The number prefix is dropped. It was decoration only: nothing links to "group 3", the jump row names sections, and earbuds and watches had to renumber their groups.
• specGroupHeading(ui, group, has5g) loses its position argument. Compare's numberedSpecGroups goes with it.
• Compare:
  • the market group heading loses its 0. too (group0Title, all 3 locales);
  • the compare CSV and JSON exports now use the same localized heading as the table, through one groupHeading helper. Before, they used the numbered English title (1. Display, and 8. Multimedia first on earbuds).
• (PhoneArena Split) is dropped from the camera heading in all 3 locales. The section eyebrow already says the grouping follows GSMArena / PhoneArena.

The same pattern elsewhere (swept locales/*.json and src for a label followed by its English name in brackets):

where	before	after
vi spec field	Vi xử lý (Chipset), Camera trước (Selfie)	Vi xử lý, Camera trước
vi spec values	8 nhân (Octa-core) (also 6 and 10)	8 nhân
vi compare rows	rowHwChipset, rowCamFront	same as above
catalogue filter headers, all 3 locales	Hãng sản xuất (Brand), Dung lượng RAM (Hardware), Tính năng nổi bật (10 field groups)	Hãng sản xuất, Dung lượng RAM, Tính năng nổi bật (en and cs likewise, cs Klíčové funkce too)
cs spec fields and messages	Hlavní snímač (Wide), Druhý snímač (Ultrawide), Přední kamera (Selfie), Standardizovaný model (Master Product)	Hlavní snímač (širokoúhlý), Druhý snímač (ultraširokoúhlý), Přední kamera, Standardizovaný model
en	Canonical model (master product)	Canonical model
vi misc	Dòng máy chuẩn hóa (master product), Cần người dùng đồng ý (opt-in), Danh mục máy tính bảng (tablet)	without the bracket

Kept on purpose:

• Acronyms: GPU, ROM, RAM, GPS, SAR, MSRP, FAQ, CORS, P/P.
• Names: DOSafe, JReviews, Official Mall, Rate Trust Score, open-core.
• Units and formats: VND, CSV, JSON, Markdown.
• "Opt-In" in the privacy text, which quotes the extension's own setting name.
• The extension API messages in server/rate/extension.ts, which are response text, not page labels.
• The leaderboard toolbar's CSV export (ProductSpecsExportToolbar, 1. Display …), an English export format.

Where the labels live: the spec labels come from the per-locale dictionaries in spec-localizer.ts. That is the existing i18n source for spec labels, shared by server pages and the client compare table. The other labels come from locales/*.json. This PR adds no hard-coded strings in components. Moving the spec dictionaries into locales/*.json would be a larger refactor, so it is not done here.

Tests

• spec-template.test.ts:
  • the compare CSV and JSON exports use groupHeading(group);
  • vi and en headings are exact;
  • no heading in any locale starts with a number;
  • no vi heading has a bracket;
  • the earbud and watch expectations are without numbers.
• product-detail-copy.test.ts: the core-count value.
• e2e/category-spec-template.spec.ts: the watch page shows Màn hình and no (Display).
• spec-template, product-detail-copy, product-spec-rows, hero-products and client-messages pass.
• tsc and eslint are clean.

Coordination

This touches only label text and its wiring. It does not touch section order (#1530) or rating blocks (#1528).

Review

• Fresh-context review: no P1. It found 2 P2s, both fixed:
  • compare still showed 0. … above the unnumbered groups;
  • the Czech labels were not swept.
• Of its P3s, these are fixed: the compare exports' numbered English group titles, the cs features count, the en gloss, and the sentence case.
• Its borderline items stay, as the keep-list above says: Mã nguồn mở (open-core) and (Mall).
• Codex round 1: no findings.
• Codex round 2: no findings.
• The Codex cap of 2 rounds is reached.

Walkthrough

Specification group headings no longer use numeric prefixes or selected English parentheticals. Product and comparison views use localized headings, including category-specific cellular labels. Locale strings and tests are updated.

Changes: Localized heading cleanup

Layer / File(s)	Summary
Localized labels and heading contract apps/web/src/lib/spec-localizer.ts, apps/web/locales/cs.json, apps/web/locales/en.json, apps/web/locales/vi.json	Specification group labels lose numbering and selected parentheticals. The specGroupHeading function no longer accepts a position and retains the no-5G cellular label behavior. Other locale labels are shortened or revised.
Product and comparison rendering apps/web/src/app/[locale]/smartphones/[slug]/page.tsx, apps/web/src/components/compare/CompareWorkspace.tsx	The product page calls specGroupHeading without a group position. Comparison views and CSV and JSON exports use localized category-aware group headings.
Heading and label tests apps/web/lib/__tests__/spec-template.test.ts, apps/web/lib/__tests__/product-detail-copy.test.ts, apps/web/e2e/category-spec-template.spec.ts	Tests expect unnumbered headings and updated localized labels, and check that comparison exports use the same headings as the table.

Estimated code review effort: 2 (Simple) | ~10 minutes

The localized heading changes are mergeable. Behavioral tests for non-English export headings would improve regression protection but need not block merging.

Full details: Description check

Explanation

The description explains the problem, changes, affected areas, testing, and coordination. It does not use every template heading or checklist item, but it is sufficiently complete and directly related to the pull request.

Full details: Linked Issues check

Explanation

Issue #1529 requires one localized label per locale, removal of decorative numbering, removal of redundant English parentheticals, and i18n-backed labels. The diff removes numbered and bilingual spec-group headings in spec-localizer.ts, removes the position parameter from specGroupHeading, and applies the helper to product pages, compare tables, and compare CSV/JSON exports. It also removes matching parentheticals from the locale dictionaries and Vietnamese core-count values. The tests verify exact localized headings, no numeric prefixes, no Vietnamese brackets, watch behavior, and export wiring.

Full details: Out of Scope Changes check

Explanation

The changed locale strings, heading wiring, and tests support the label cleanup requested by issue #1529. The market heading cleanup and the catalogue, specification, and related page-label updates address the same bilingual-label pattern. No unrelated feature, section-order, or rating-block change is present in the reviewed diff.

Follow-up Comments

Test the export heading output, not only the call sites.

221-223: Trivial · Maintainability & Code Quality · Poor tradeoff

Test the export heading output, not only the call sites.

The two new assertions in spec-template.test.ts check only that CompareWorkspace.tsx contains the text groupHeading(group). If groupHeading returned group.title for every group, both assertions would still pass. No test checks downloaded CSV or JSON group titles in a non-English locale. Move the heading logic into a function that the test can call, then assert its output for vi and cs.

Update the export heading logic referenced by CompareWorkspace.tsx so it lives
in a function that tests can call, then replace the source-text assertions in
spec-template.test.ts with output assertions verifying the group titles for
Vietnamese (vi) and Czech (cs) locales; cover the heading behavior used by both
CSV and JSON exports.
