JP locale: CD Walkman / MD Walkman naming cleanup

Summary

• Goal completed: JP-facing archive labels now use CDウォークマン and MDウォークマン
• Scope: presentation-layer Japanese labels only unless broader touchpoints were required to keep JP output consistent
• Validation style: static inspection only

Files modified

• src/components/AudioFamilyNav.astro
• src/data/books.ts
• src/data/reference/locales/jp/archive-updates-jp.js
• src/data/reference/locales/jp/discman-articles-jp.js
• src/data/reference/locales/jp/header-nav-jp.js

• src/data/ui/ui-strings-safe.js
• src/data/ui/ui-strings.js
• src/lib/archiveSearch.ts
• src/lib/localizedYearLabels.ts
• src/pages/about.astro

What changed

The Japanese presentation layer was updated so the archive now presents:

• ディスクマン as CDウォークマン
• MiniDisc / ミニディスク as MDウォークマン

This was applied across JP-facing category and taxonomy surfaces, including:

• primary family navigation
• JP header navigation labels and panel labels
• collections and articles category labels
• year-guide labels and localized year headings
• JP article titles and subtitles for Discman and MiniDisc year pages
• search scope labels and search result family labels
• JP archive copy used in search and hub descriptions
• timeline description copy
• JP-facing archive summary text in related shared content

Safety notes

Internal identifiers, routes, slugs, filenames, and core family keys such as discman and minidisc were preserved.

The update was kept at the Japanese presentation layer. A few shared files outside src/data/reference/locales/jp were touched only because they are responsible for rendering JP-facing labels:

• src/components/AudioFamilyNav.astro
• src/lib/archiveSearch.ts
• src/lib/localizedYearLabels.ts
• src/data/ui/ui-strings-safe.js
• src/data/ui/ui-strings.js
• src/pages/about.astro
• src/data/books.ts

Preserved historical uses

Historical or explanatory body text that still refers to Discman or MiniDisc was intentionally left in place when it functions as archival narrative rather than UI taxonomy.

Examples:

• src/data/reference/locales/jp/discman-articles-jp.js
• intro and conclusion lines discussing the historical Discman era were preserved
• reason: these lines describe the period term, not the archive's current category label

• src/data/reference/locales/jp/minidisc-articles-jp.js
• narrative body lines discussing MiniDisc as a historical format were preserved
• reason: these are historical explanations rather than current navigation or taxonomy labels

• src/data/reference/locales/jp/minidisc-collections-jp.js
• long intro text that discusses MiniDisc historically was preserved
• reason: explanatory collection context

Final confirmation

The Japanese archive now presents the updated naming consistently across the major taxonomy surfaces without changing the underlying site structure.

Some preserved historical narrative uses of Discman and MiniDisc remain by design in archival body copy.

JP locale: メモリーウォークマン rename

Summary

• Replacements made: 86
• Goal completed: JP user-facing category and label usage now uses メモリーウォークマン
• Validation status: passed

Files modified

• src/components/AudioFamilyNav.astro

• src/pages/networkwalkman/articles/[slug].astro
• src/pages/networkwalkman/index.astro
• src/pages/search.astro
• src/pages/walkman/[slug].astro

What changed

The rename was applied only to JP-facing category and label surfaces:

• navigation labels
• family navigation defaults
• category headings and filter labels
• search scope labels and search result family labels
• article card titles/subtitles
• collection titles/subtitles
• timeline/category labels
• JP SEO/fallback strings that were still surfacing Network Walkman on Japanese pages

Internal identifiers, routes, slugs, filenames, and non-JP locale labels were left unchanged.

Preserved historical uses

The old wording was intentionally preserved where it is part of archival or explanatory context:

• src/data/reference/locales/jp/networkwalkman-articles-jp.js
• preserved in historical narrative lines such as the 1999 brand introduction and later retrospective conclusions
• reason: these lines describe the official historical branding, not the current archive UI label

• src/data/reference/locales/jp/networkwalkman-collections-jp.js
• preserved in collection intro text
• reason: these intros explain historical phases and product context

• src/data/reference/locales/jp/networkwalkman-descriptions-jp.js
• preserved across model descriptions and long descriptions
• reason: these are archival descriptions tied to period-correct Sony branding and historical interpretation

• src/data/reference/locales/jp/spotlight-jp.js
• preserved in long-form narrative text
• reason: explanatory historical context

Validation

Source search

Searched again for both:

• ネットワークウォークマン
• Network Walkman

Result:

• remaining JP occurrences are limited to historical/archive narrative content and model descriptions
• remaining non-JP or internal occurrences are outside the requested scope

Built output check

JP verification build was run with:

• npx astro build --outDir dist-jp-memory-walkman-verify

Result:

• build completed successfully
• sitemap integration also completed successfully in the verification output

Targeted built-page checks on:

• dist-jp-memory-walkman-verify/jp/articles/index.html
• dist-jp-memory-walkman-verify/jp/collections/index.html
• dist-jp-memory-walkman-verify/jp/networkwalkman/index.html
• dist-jp-memory-walkman-verify/jp/search/index.html
• dist-jp-memory-walkman-verify/jp/books/sony-personal-audio/index.html

confirmed that old-term label usage no longer appears there, and メモリーウォークマン is rendered instead.

Final confirmation

No user-facing JP category, nav, heading, card, filter, search scope, search result family label, or JP fallback SEO label remains using:

• ネットワークウォークマン
• Network Walkman

Any remaining JP-source occurrences are preserved historical or archival references by design.
