2. How to “Update” a Theme

Updating means replacing or modifying the existing CSS code.

V. Motion and the Ethics of Movement

Motion is permission; it can direct, delight, or distract. In Emby’s context, animation should be a gentle usher, not a carnival barker: crossfades between posters, eased transform on hover, and restrained parallax behind metadata. Respect the viewer’s stamina — too much motion fatigues and betrays the stillness that cinema asks of us.

Option A: Replace Entire CSS

1. Copy new/modified CSS.
2. Paste into Custom CSS (overwrite old).
3. Save → Restart Emby Server or hard refresh browser (Ctrl + Shift + R).

II. The Materiality of Light and Shadow

Light in UI is a politics. A pale background invites daylight, clarity, the illusion of emptiness; dark backgrounds fold content into the thingness of objects, privileging focus and mystery. For Emby, where posters and stills are the primary artifacts, shadow is a curator: drop-shadow that suggests depth, vignette that frames nostalgia, gradient overlays that push titles forward like captions whispered in a dark theater.
