Key changes
- Added ADR
2026-02-07-007-tools-implementation-structure - Defined a rule to keep page-entry files thin and move implementation into
src/features/tools/[tool-slug]/ - Documented i18n ownership: keep tool copy local by default, and promote only reused strings to
src/i18n
Goal
Make tool boundaries explicit so new tool work stays maintainable without bloating global i18n.
