Render a single-word emblem Fortis with F uppercase and the rest lowercase, built entirely from advanced Unicode block art. Use only: blocks (█ ▓ ▒ ░ ▀ ▄ ▌ ▐), box-drawing (─ │ ┌ ┐ └ ┘ ├ ┤ ┬ ┴ ┼ ╭ ╮ ╯ ╰ ╱ ╲ ╳), quadrant blocks (▖ ▗ ▘ ▝ ▞ ▟ ▙ ▛ ▜ ▚), double lines (═ ║ ╔ ╗ ╚ ╝ ╠ ╣ ╦ ╩ ╬), shading blocks (░ ▒ ▓), and braille fillers (⣿ ⣶ ⣤ ⣀ ⠿ ⠶ ⠤ ⠄). Style: a 3D isometric extrusion toward the lower-right, with diagonal edges using ╱ and ╲, side faces shaded in ░▒▓. Output as a single monospace block (no color, no frames, no commentary). Maximum height eight lines; width proportional. Letters: F upper-case, others lower-case, forming Fortis.. Emphasize a cohesive composition, cinematic lighting, vivid details, strong subject focus, and layered depth.

The image shows the word "Fortis" spelled out in white letters on a black background. The font is bold and stands out against the dark background, creating a striking contrast.
