CLI wordmark (egregiously) violates brand guidelines

[mynameistito]

Description

Problem

The wordmark shown when doing opencode upgrade does not adhere to brand guidelines. The E and N letters are missing the inner shadow effect that other letters have, resulting in an inconsistent appearance compared to the official wordmark.

Previously mentioned: #8583 but for TUI

This issue is closely related to the TUI wordmark fix:

• TUI wordmark (egregiously) violates brand guidelines #8583: TUI wordmark (egregiously) violates brand guidelines

Since #8583 has already been closed, this CLI wordmark issue appears to be a follow-up that needs the same fix applied to the CLI upgrade command. The solution or approach from the TUI fix may be helpful for resolving this CLI issue as well.
