Retake the screenshots and cut the Metadata section down to its neighbours' size

[revtex]

Three problems, all in the README.

Every screenshot predated the Metadata tab. The nav strip in all three showed four tabs where the app has five — the first thing a reader compares against their own window, and it disagreed.

The Advanced shot was worse than stale. It still showed the three advertisement switches that 0.2.0 replaced with a single Record dropdown, two filename presets instead of five, and a line of prose under each setting from before those became tooltips. Someone following it would have gone looking for controls that are not there.

The Metadata section did not read like its neighbours. 64 lines against 28 and 38 for the sections either side, and the only UI section with no screenshot at all.

What changed

settings.png and advanced.png are retaken from a staged profile, which is why the paths read C:\Music\Offstream and C:\ffmpeg\bin\ffmpeg.exe — both are the examples the surrounding prose already calls examples, and neither carries a real user name. Settings is cropped to 990px as it was before, keeping the footer's absolute settings path out of a published image. Its provider now reads Last.fm rather than Nothing, so the image agrees with the paragraph below it that says Offstream starts with Last.fm selected and asks for a key on first run.

metadata.png is new: the scanned library on the left with cover art and Will change badges, the editor for the selected track on the right, and the search box pinned to the foot of the pane.

The section itself drops from 64 lines to 49 — and that now includes the screenshot, so the prose fell further than the count suggests. Two paragraphs were doing work the image does better: the list beside the editor, the ten field names, the was … line, the badge. Those become the image plus four lines.

What is kept in words is the part an image cannot show:

• clearing a box stops Offstream changing that tag rather than erasing it
• a comma separates genres but not names, because "Earth, Wind & Fire" is one band

The rationale for why the editor sits beside the list instead of inside the row is design history. It belongs in docs/MODERNIZATION-PLAN.md, where it already is, not in a page telling someone how to retag a file.

What is deliberately not here

record.png is untouched. Its only fault is the missing tab, and an honest replacement needs Spotify playing into a live recording — the cover art, the moving level meter and the elapsed clock are what make it the page's hero shot, and none of it can be staged.

Verification

• .\build.ps1 -VerifyFormat — clean.
• Both retaken pages captured from this branch's build, so the five-tab nav strip is consistent across all three new images.
• Staging (C:\Music\Offstream, C:\ffmpeg\bin, the temp profiles) removed afterwards; the real %APPDATA%\Offstream\settings.json was never written to — every capture ran under OFFSTREAM_HOME.

no-changelog: nothing about the shipped application changed.
