Philosophy
The name Blue PSL 10K is a playful nod to:
- PSL — Pumpkin Spice Latte (Catppuccin's coffee-inspired naming) and Posh Segment Latte (Oh-My-Posh + Latte)
- 10K — The legendary PowerLevel10K prompt that inspired the prompt styling
- Blue — The custom
#3465a4 path/directory color that unifies the theme
