   Job Hunt with Hope — agenthope.ai
   Premium booklet styling, design-cookbook conformant. Same visual language
   as the Hope portfolio: warm cream + orange, Inter + JetBrains Mono, mono
   eyebrows with a glowing dot, scanline/grid textures, soft-shadow cards with
   a hover lift, per-step accent colors. Light by default; dark via the toggle.
   Fully readable with JavaScript OFF (the toggle is progressive enhancement).
