From f530185e3110e3db6872513b599f5a3ed391a83b Mon Sep 17 00:00:00 2001 From: Matt Edholm Date: Wed, 22 Apr 2026 23:27:36 -0400 Subject: [PATCH] =?UTF-8?q?feat(renderer):=20implement=20per-aircraft=20dr?= =?UTF-8?q?awing=20=E2=80=94=20story=202-5?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implements draw_aircraft() with heading arrow (filled/outlined for MLAT), callsign+altitude label, and a 5-dot fade trail. Adds 5 tests covering all ACs; all 94 tests pass, ruff lint and format clean.
