// Bilingual (Chinese/English) UI string table. The language lives in cfg.lang (switched on the provisioning
// page) and the strings themselves live in PROGMEM; TR() copies one into a rotating buffer and returns a
// plain const char* (usable directly by u8g2 / snprintf). That saves about 1.5 KB over keeping both sets in
// RAM -- this board is far tighter on RAM than on flash.
// Note: at most TR_SLOTS(6) TR() calls may appear in one expression, the format string itself counting as
// one; a single string is limited to 71 bytes.

enum Lang : uint8_t { LANG_ZH = 0, LANG_EN = 1 };
// X-macro: the enum and the string table expand from one definition, so they can never drift apart.
// English strings are ASCII only (the 32-126 range of the bitmap font); entries that are identical in both
// languages are written twice and the compiler merges the duplicate literals.
