VoC interpretations ship in en, ru, es, de, fr, it, pt, zh, uk, ja, ko, hi, ar, tr, nl, pl, plus en-GB and regional variants - 22 in total.
Language-first fallback: request event-oriented + ar and the response returns Arabic, not English with an Arabic header.
The previous fallback chain dropped to English when a specific tradition lacked a translation; the new chain checks the language first, then walks the tradition tree.
19 traditions are supported, from Hellenistic to medieval Arabic to Renaissance European, with 831 interpretation keys total across the VoC + planetary hours + antiscia surface.
For non-English markets this is the difference between a usable product and a translation ticket.
