What changes

  • Social card - "Test sets, not just files." with presets, recipes and per-format settings on the left, and the presets above the manifest one of them writes on the right. GUI + CLI beside the name. The format count and the preset list come from the registry. The same picture is already uploaded as the repository's social preview on GitHub.
  • README - a table of every preset and the question it answers, right after the formats. Install and Quick start move up under the table of contents, their text unchanged. The animation and the four window screens are 0.4.0.
  • Site - the first picture is the 0.4.0 window, with its new height.

Guards

  • TestTheReadmeListsEveryPresetItShips - the README's preset table against the registry, in both directions, the question word for word. Three mutation entries.
  • TestTheSocialPictureShowsTheCardAsItIsNow now says to upload the picture to GitHub as well, because GitHub keeps a copy of its own that nothing here writes to.

A generator of one file at one size loses to the ones in a browser, so the
card now says "Test sets, not just files." and names presets, recipes and
the settings each format takes, with the presets above the manifest one of
them writes. The count of formats and the list of presets come from the
registry. GUI + CLI stands beside the name, so it does not read as a tool
for CI alone.

GitHub keeps its own copy of the picture, uploaded by hand, and it said 24
formats while this one said 26. The guard that turns red when the card
changes now says to upload it there as well.

…as it is today

The presets section named no preset and sat in the reference half. It now
stands right after the formats, with a table of every preset and the
question it answers, and a guard compares that table with the registry in
both directions, word for word. Install and Quick start move up under the
table of contents, their text unchanged.

The animation and the window shot were of an older window. Both are replaced
with 0.4.0, the desktop window section shows four of its screens, and the
site's first picture carries its new height.

📝 Walkthrough

Walkthrough

The README reorganizes installation and quick-start guidance, adds a preset guide and desktop screenshots, and checks its preset table against registered presets. The social preview card now presents product capabilities, presets, and size-boundary examples. Related image dimensions, digest, and stale-card guidance are also updated.

Changes

Product documentation and presentation

Layer / File(s) Summary
Installation and quick-start guidance
README.md
The Install and Quick start sections move earlier in the README and add Go version, signing, renderer, and generation guidance. The earlier sections are removed from their former location.
Preset reference and validation
README.md, internal/guard/readmepresets_test.go
The README describes six presets, adds commands and notes about show and eject, and adds desktop screenshots. The guard test checks that the preset table matches registered presets.
Social preview card and metadata
web/templates/social.html, web/content/en/index.html, web/content/pl/index.html, web/social-preview.sha256, internal/guard/socialpicture_test.go
The card presents capabilities, preset chips, and a manifest with three size-boundary examples. The hero image height and stored digest change. The stale-card message adds upload guidance and a release-check reference.

This is a documentation and preview refresh with a guard test. The remaining issues are small: a misleading failure message, a guard that misses duplicate rows, and card sample values that are not checked against actual preset output. None affects runtime behavior.

Explanation

The social preview changes the established term your system should to your app should in the manifest heading (web/templates/social.html:236). The README and site consistently describe the software under test as your system or system under test. These labels refer to the same concept, so the PR introduces inconsistent user-facing terminology.

format-count incident details and the reference to `tools/release-check.py`,
which does not exist. Keep the instruction to upload the image manually through
GitHub Settings, General, Social preview, and retain the statement that GitHub

Review comments at @web/templates/social.html:

owner and dates while preserving the stated reasoning. Update both the opening
comment and the badge comment; leave unrelated comments unchanged.
- Around line 237-239: Add a guard test for the manifest rows in the social
template that generates the 1 MB size-boundaries preset and compares its file
names, byte counts, and outcomes with the displayed rows. Keep the test focused
on detecting drift between the preset output and these literals.

No registry mismatch is established.

The hard-coded copy matches the shipped presets and documented capabilities. It does not duplicate a generated name, number, or table that must be data-driven. No correction is required.

Remove the nonexistent tool reference and dated history.

tools/release-check.py is not present in the repository. Remove both the false comparison claim and the time-sensitive incident details. Keep the GitHub upload instruction.

Hard-coded manifest rows can drift from what size-boundaries writes.

The comment at Lines 19-20 says these are real values. The file names, byte counts and outcomes are literals. The digest guard only detects changes to the template, not a change in preset output. Add a guard test that generates size-boundaries for 1 MB and compares the file names, sizes and outcomes to these rows.

The social card, the README and the site's first page in both languages
show the same three files - one byte under a 1 MB limit, the limit, one
byte over - as literals, and the card says everything on it is real.
TestTheLimitExampleIsWhatThePresetWrites runs the command the README and
the site print, as a dry run, and holds all four places to the names, byte
counts and outcomes the manifest declares. The card before this one printed
a shorter command that the program refuses.

The presets table guard refuses a second row for one preset, which could
hide a wrong question behind a right one. "ready-made" is hyphenated, and
the card's comments give the reasoning without a date.

Outside review of #148.
