[ANN] Blueshore - open source skins (light + dark) for the Zimbra Classic UI

[Gianluca Zamagni]

Hi all, 

I run Zimbra FOSS (Maldua builds) for my company's mail. The Classic UI 
is still the most solid way to use Zimbra, but the stock look has aged 
badly, so I restyled it and open sourced the result. 

Blueshore is a family of four colour-matched skins built from a single 
shared source: 

- Tide (blue) and Sand (amber), each in a light and a dark variant 

- every icon redrawn as inline SVG (Lucide), no legacy sprites 

- Public Sans typeface bundled with the skin, zero external requests 

- denser, quieter layout; proper dark mode (calendar, native form 
controls, editor toolbar - message body stays a light card, since 
HTML mail assumes a white background) 

- plain skin, no core patches: copy into skins/, zmskindeploy, enable 
with zmprov; it survives upgrades and users pick it per account in 
Preferences -> Theme 

- palette-based build tooling included: a custom branded variant is one 
.properties file with your colours 

Developed and tested on Zimbra FOSS 10.1.18 (Maldua). AGPL licensed.

Feedback, issues and palettes are welcome.
