Closes#578. Rewrites the user file library save-mode description in the English database.md and architecture.md guides (independent-new by default, parent-linked on overwrite) and updates all 20 translated copies of each, with i18n_source_hash re-stamped so the parity gate stays green.
Independent reviewer agents checked all 20 locales of guide/low-resource plus the two cross-link paragraphs against the English source. 26 fixes across 12 locales (fr calques, tr/ru terminology drift, a zh-CN crop-vs-trim meaning error, a zh-TW garden-path sentence, ko particles, de collocations, es calques, small id/vi/th/sv fixes); 8 locales clean. Parity check and VitePress build pass.
Admin merge: docs-only PR, path-filtered required contexts never report (#420 precedent).
New guide/low-resource page: what runs well on 2 GB machines, a Raspberry Pi / old laptop Compose walkthrough with tuned caps, the env-var knobs that matter on small hardware, and what to skip. Linked from getting-started, the deployment hardware section, and the sidebar. Translated into all 20 non-English locales via the i18n batch pipeline; parity check and VitePress build pass.
Admin merge: docs-only PR, the path-filtered required integration contexts never report (#420 precedent).
Closes#497
All 181 docs markdown files translated into 20 languages (apps/docs/<locale>/**). Companion to the i18n code PR; admin-merged because the file count exceeds GitHub's per-PR CI trigger limit. Validated by pnpm i18n:check (all surfaces, 0 stale/missing) and a clean all-locale docs build.
