@lunabright3 A handheld selfie vlog-style video in vertical 9:16 format.

Luna stands under streetlights, holding the phone close but not rigidly.

The camera subtly drifts as she adjusts her grip and breath.

She maintains eye contact with the camera for a few seconds, then relaxes her gaze.

Her expression is steady and assured, without posing.

Mood: present, grounded, still moving forward.
