Two complete catalogs, hi and ko, 2,578 entries each (every (context, English) key the bundled catalogs hold), registered in LANGUAGES (24 -> 26) and in the date languages (hi, ko). Both use a single @plural form. Korean has no Hangul face in craft-fonts, so desktop builds draw it with one installed face (Malgun Gothic, Apple SD Gothic Neo, Nanum; never Noto CJK / Source Han), added after the embedded faces like the Devanagari fallback. PDFCRAFT_SYSTEM_FONTS=0 turns it off. Tests: catalog registration and persistence, command / All tools / tl!() literal coverage for both, date names, Hangul fallback and candidate list. cargo xtask assets, fmt and clippy are clean. Also refreshes the ru.tsv SHA-256 in ATTRIBUTION.toml and the docs. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
