fix(gui): improve header and button color contrast (fixes #10488) (#10815)
### Purpose

Improve the contrast of semantic request-dialog headers and buttons in
the light, dark, and black GUI themes.

The light theme keeps its bright semantic colors and uses black text for
success, warning, and danger alerts plus success/warning buttons. Danger
buttons use the existing darker red with white text. The dark themes use
darker success, warning, and danger backgrounds with white text.

The lowest enabled-state contrast ratio is 4.509:1, meeting WCAG AA for
normal text.

### Testing

- `go run build.go assets`
- `go run build.go build syncthing`
- `git diff --check`
- Checked the base and interactive semantic color pairs with a WCAG
contrast calculation; all enabled states are at least 4.5:1.
- Loaded the generated GUI assets in Chromium and verified the computed
foreground/background colors for success, warning, and danger alerts and
buttons in both light and dark themes.

### Screenshots

Rendered light and dark fixtures locally to verify the complete alert
and button combinations. The computed colors matched the intended theme
rules and no clipping or layout changes were introduced.

### Documentation

No documentation changes are required; this only corrects existing theme
colors.

Syncthing


MPLv2 License CII Best Practices Go Report Card

Goals

Syncthing is a continuous file synchronization program. It synchronizes files between two or more computers. We strive to fulfill the goals below. The goals are listed in order of importance, the most important ones first. This is the summary version of the goal list - for more commentary, see the full Goals document.

Syncthing should be:

  1. Safe From Data Loss

    Protecting the user's data is paramount. We take every reasonable precaution to avoid corrupting the user's files.

  2. Secure Against Attackers

    Again, protecting the user's data is paramount. Regardless of our other goals, we must never allow the user's data to be susceptible to eavesdropping or modification by unauthorized parties.

  3. Easy to Use

    Syncthing should be approachable, understandable, and inclusive.

  4. Automatic

    User interaction should be required only when absolutely necessary.

  5. Universally Available

    Syncthing should run on every common computer. We are mindful that the latest technology is not always available to every individual.

  6. For Individuals

    Syncthing is primarily about empowering the individual user with safe, secure, and easy to use file synchronization.

  7. Everything Else

    There are many things we care about that don't make it on to the list. It is fine to optimize for these values, as long as they are not in conflict with the stated goals above.

Getting Started

Take a look at the getting started guide.

There are a few examples for keeping Syncthing running in the background on your system in the etc directory. There are also several GUI implementations for Windows, Mac, and Linux.

Docker

To run Syncthing in Docker, see the Docker README.

Getting in Touch

The first and best point of contact is the Forum. If you've found something that is clearly a bug, feel free to report it in the GitHub issue tracker.

If you believe that youve found a Syncthing-related security vulnerability, please report it by emailing security@syncthing.net. Do not report it in the Forum or issue tracker.

Building

Building Syncthing from source is easy. After extracting the source bundle from a release or checking out git, you just need to run go run build.go and the binaries are created in ./bin. There's a guide with more details on the build process.

Signed Releases

Release binaries are GPG signed with the key available from https://syncthing.net/security/. There is also a built-in automatic upgrade mechanism (disabled in some distribution channels) which uses a compiled in ECDSA signature. macOS and Windows binaries are also code-signed.

Documentation

Please see the Syncthing documentation site [source].
