Add a 'Implémentation Cosma — antenne Kogger' section to the page that ties the
abstract protocol (DS-TWR / SS-TWR / addressed) shown in the animations to the
concrete hardware driver used in the Cosma project (cosma-tech/kogger_acoustic
Antenna), and to the new wrapper poulpe/kogger-transpondeur-continu that turns
a Kogger antenna into a permanent slave transponder in a single start() call.
Add a 'Sources' section listing all four related repos (this page, wrapper,
upstream driver location, log decoder).
Update README similarly with a 'Hardware companion repo' section so the
ping-pong-ping repo no longer reads as standalone — it's the protocol
explainer, kogger-transpondeur-continu is the hardware glue.

Two fixes for the visual confusion of 'A appears to send two pings back to back':
1. Add 600 ms (sim) guard interval between cycle N's tPing2Recv and cycle N+1's
tPing1Send. Removes the visual hiccup where ping2 (end of cycle N) and ping1
(start of cycle N+1) collided as two consecutive A→B cyan pulses.
2. Distinguish ping2 from ping1 visually: ping1 = solid filled circle, ping2 =
hollow ring (same cyan color). Legend updated. The user can now tell at a
glance which transmission is which without relying on the small label text.
Reported by Flag 2026-04-27, fixed same day.
Self-contained HTML demo with two interactive canvas animations:
- Animation 1: DS-TWR principle (mobile-mobile, both sides know distance)
- Animation 2: USV master + N AUVs, SS-TWR active + passive OWR for non-target listeners
Realistic AUV operating params (1-2 kt cruise, 5-700 m range).
Includes README documenting the protocol, design decisions taken during the
2026-04-27 design conversation between Flag and Poulpe, deployment routing
(Gateway Caddy + Core Caddy path-based), and TODO for future iterations.
