From e93f5593e268cab77984fc98913728d22e0ceb4c Mon Sep 17 00:00:00 2001

Subject: [PATCH] =?UTF-8?q?fix:=20final=20map=20implementation=20=E2=80=94?=
 =?UTF-8?q?=20iframe=20+=20style.json=20+=20fill-antialias:false?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Three-part fix for retina tile seam artifacts:
1. iframe isolation from Hugo Tailwind CSS (box-sizing interference)
2. Use tileserver style.json URL (not inline style — different layer configs)
3. fill-antialias: false on choropleth layer

Shortcode is now a thin iframe wrapper. Map logic in static/map-embed.html.
