Walkthrough

The MOTD header in flb_motd.h is replaced with a concise linear banner. The flb_motd_text byte sequence is rewritten, removing decorative multi-line ASCII art and replacing it with simpler banner text. No public declarations are altered; only the embedded string data changes.

🐰 The MOTD banner now stands lean and bright,

Directs ahead in every way! ✨

23-73: LGTM! Clean banner update for v4.2.

The MOTD banner has been properly updated with the new version information. The hex-encoded text correctly represents "Fluent Bit v4.2 – Direct Routes Ahead" along with the 10-year celebration message. The array is properly null-terminated and the encoding is accurate.

One minor note: The banner includes a UTF-8 en-dash character (0xe2, 0x80, 0x93 at line 65). This is generally well-supported, but you may want to verify it renders correctly across all target terminal environments if compatibility is a concern.
