ABCG Agenda Embed

Makes the agenda iframes on abcg.ch size themselves to their content, so the inner right-hand scrollbar disappears and nothing is cut off.

The problem

The two agenda boxes are iframes served from admin.abcg.ch, a different host than abcg.ch. A browser will not let a page measure the content of an iframe from another host, so the height had to be hard-coded:

• Home page — no height at all, so the browser fell back to a default that is too short on phones.
• /agenda/ — fixed at 1300px, while the real content is roughly 2100px on desktop and 2900px on a phone. Everything past 1300px sat behind the scrollbar.

The content height also changes with screen width, so no fixed value can be correct on every device.

How it works

The plugin serves the two agenda pages from this domain (/abcg-embed/next/ and /abcg-embed/list/). Because the iframe is then same-origin, its real height can be read and reported to the page, which resizes the frame to match.

On the way through, the plugin also:

• keeps the ASP.NET postback working (the "Lire plus ..." detail box), including ViewState and session cookies, so the frame re-sizes when the box opens and closes;
• lifts the fixed height: 80px on the home page cards, which was slicing long event titles in half;
• stacks the agenda date above the title below 780px, so rows stop spilling sideways on a phone.

Only those two pages can be requested — the endpoint is not a general proxy.
