Three captures of /blog/engineering/delayed-gratification-in-ai-summer
taken with rodney (headless chromium):
- external-link-hint-icon.png: a paragraph as rendered - the marker icon
follows the external link, the hint text is invisible
- external-link-hint-unhidden.png: same paragraph with the sr-only rule
cancelled, showing " (opens in a new tab)" inside the link, which is
what screen readers get
- external-link-hint-page.png: full page for context (internal links such
as "Swim the Test" carry no icon)
Backing evidence, from the same load: the accessibility tree names exactly
the 8 external links with "opens in a new tab"; the hint box measures
1x1 with clip-path inset(50%).
