A tiny typed i18n layer (no library): en.ts is the single source of UI
copy and the clarity rewrite lives there — shorter sentences, plain
words, the dense Methodology/Scoreboard copy untangled. de.ts mirrors
its shape exactly, enforced by the compiler, with placeholder parity
covered by tests. Every page now reads from the dictionary via useT();
dates flip locale through useFormat() (en-GB/de-DE); raw server values
(status, outcome, stage) map through total records.
The header gains an EN/DE toggle (persisted, defaults from the
browser language); <html lang> stays in sync.
