amendment: 2026-A3 Duties of the Social Media Manager

[TianLangHin]

Rationale

• To ensure Marketing Directors do not need to split their attention between promotional material creation/management and social media account management, the Social Media Manager role is proposed to be made.
• This role is defined to be distinct from the Marketing Directors' duties, revamping the demarcation of roles in the Constitution before the 2026 amendments.
