What changed and why

Follow-up to #678. A long source text in the incident card scrolled inside the card, so the popup had two scroll areas. In a stack of conditions, the card scrolled inside the popup's own scroll.

Now the card has no inner scroll area:

• A short text (up to about five lines) prints in full.
• A longer one shows its first four lines, fading out, then "Show more" in the theme's brand green. "Show more" opens the full text in place, and "Show less" closes it.
• The popup itself is the only scroll area. It scrolls only when opened text or a stack of conditions outgrows 60% of the screen, which now applies to single cards too.

The toggle is a native <details>, so it works by keyboard and needs no script in the HTML-string popup. The full text is always in the card; the toggle only removes the fade and height limit.

Long source text (A42 congestion, NDW)

Each image shows the card closed on the left and opened on the right.

These images are the branch's card HTML with the branch globals.css in a standalone page, not the live map. The text is the A42 report from the review screenshot. Mobile viewports were not captured.

Verification

• vitest --project node: 1,362 files, 18,495 tests passed. vitest --project web: 590 files, 5,604 passed.
• tsc --noEmit -p tsconfig.integrations.json: clean. Biome on changed files: no errors. check-translations: no errors.
• New test: a short text has no toggle; a long one has the whole text plus the "Show more"/"Show less" toggle.
• In a browser, neither the closed nor the opened card contains a scrolling element.
