feat: binary glow effects, refined drawings and calls to action

Dark surfaces now carry light: frames glow along their edge and shed binary
digits (BitAura), dark sections open with a lit seam (BitSeam), the career
path is a line of light and "My work" became a dark stage. Buttons carry a
travelling light and a spot that follows the pointer (BitGlow).
