Redesign wings startup banner - #204
Conversation
Replace the plain boot banner with an ANSI Shadow "PELICAN" wordmark rendered in a vertical cyan->blue gradient, followed by a WINGS rule with the build version centered beneath it, a tagline, aligned Source/Docs link rows, and a star-the-project call-to-action. Color depth adapts to the terminal: 24-bit truecolor when COLORTERM advertises it, a 256-color approximation otherwise, and no escape codes at all when stdout is not a TTY. The runtime copyright/MIT block is dropped (still shipped in the LICENSE file), and the log-path notice now prints below the banner.
📝 WalkthroughWalkthroughStartup output now reports the configured log path directly. The previous logo and license text were replaced with a terminal-aware Pelican banner that supports multiple color modes and includes version, links, and a GitHub star call-to-action. ChangesStartup output

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Return plain output when color is disabled.
A character device does not guarantee 256-color support. TERM=dumb terminals receive literal ANSI escape sequences from this branch. Users who set NO_COLOR also receive color output.
Return bannerPlain before the color-mode switch when TERM is "dumb" or NO_COLOR is set.
Proposed fix
func detectBannerColor() bannerColor {
fi, err := os.Stdout.Stat()
if err != nil || fi.Mode()&os.ModeCharDevice == 0 {
return bannerPlain
}
+ if os.Getenv("TERM") == "dumb" || os.Getenv("NO_COLOR") != "" {
+ return bannerPlain
+ }
switch os.Getenv("COLORTERM") {📝 Committable suggestion
