**flip v0.1.1**

flip captures a document one page at a time. Point it at a window, drag a box
around the page, and it turns each page, waits for the redraw to settle, and
captures it - until you have a folder of images or a single PDF.

**What changed since v0.1.0**

• **Light/dark theme toggle** in the title bar. The choice is remembered across
restarts.
• **Links moved.** The author's GitHub account was renamed from `hoijun-kim` to
`hoijunkim`, so the repository is now `github.com/hoijunkim/flip`, the landing
page `hoijunkim.github.io/flip`, and the winget package `hoijunkim.flip`. Old
links survive only while GitHub redirects the previous account name, which
stops if someone else claims it.
• **CI** now asserts cgo-free correctly. The old check compared against an array
rather than a string, so it could pass without proving anything.

**Install:** download the zip, unblock it (right-click the zip > Properties >
Unblock, or it stays flagged as downloaded), extract `flip.exe`, and run it. No
installer, nothing written outside where you point it.

**This build is not code-signed.** Windows SmartScreen will warn on first run:
"More info" > "Run anyway". That warning is expected for an unsigned exe from a
small project, not a sign of anything wrong; verify the download with the
published SHA-256 if you want certainty.

**What flip does not do:**

• It does not defeat capture protection. A DRM reader (some ebook viewers) tells
Windows not to let its window be captured, so a capture of it reads solid
black - flip detects that at preflight and stops rather than working around
it. Use flip on content that is yours to reproduce.
• It is Windows-only.

**Before you trust a long capture, check these once on your setup** (they have
been built and unit-tested but never run end to end on the author's machine):

1. **The abort key.** Start a capture and press `Ctrl+Shift+F9` - it must stop
the run. flip takes over the keyboard while capturing; this is how you get
out.
2. **Your viewer accepts the page-turn key.** Some viewers ignore synthetic
input. Preflight cannot tell in advance - the first few pages will.
3. **Integrity.** If your document viewer runs elevated and flip does not,
preflight marks the target "cannot send keys" - run flip as administrator, or
the target at the same level.
4. **One real page turn.** Capture five pages and check the count matches the
pages that actually turned, with no duplicate or miss, before running a whole
book.
