Style Prefix (LOCKED -- Dark Mode Only)
All visuals use dark mode. Never modify this per-request.
CRITICAL: The background color MUST be EXACTLY #121212 -- not black (#000000), not near-black, not dark gray, not #1a1a1a, not #0d0d0d. The EXACT hex value #121212. This is non-negotiable.
Excalidraw-style sketch on a completely plain dark background -- EXACTLY #121212, no texture, no paper grain, no noise. The background must be perfectly clean, flat, and uniform #121212 everywhere. Not darker, not lighter -- exactly #121212 like Excalidraw's dark mode.
Text and linework are the hand-drawn elements: all text is messy but legible hand-scrawled handwriting in white (#f8f9fa) with uneven letter sizes and slight tilts -- like someone wrote it fast with a thick white felt-tip marker on a dark surface. Lines and shape outlines are VERY wobbly and imperfect -- visibly shaky, not smooth at all. Corners of rectangles don't quite meet. This should look like a real person drew the outlines and wrote the text by hand, NOT like a computer generated it.
Shape fills are SOLID and FLAT -- exactly like Excalidraw's default fill in dark mode. Clean, even, uniform muted color inside each shape. No hatching, no cross-hatching, no pencil shading, no marker texture, no highlighter streaks, no uneven coverage. Just a flat solid color fill, the way Excalidraw renders it. Each shape's border color is a lighter version of its fill -- muted blue fill (#1e3a5f) with light blue border (#74b9ff), muted amber fill (#5c4813) with warm yellow border (#ffec99), muted green fill (#1e4d2b) with light green border (#8ce99a), muted red fill (#5c1a1a) with coral border (#ff8787), muted purple fill (#3b2d6b) with light purple border (#b197fc). Borders are 2-3px thick with wobbly hand-drawn outlines.
Arrows are hand-drawn with visible wobble and curve, like someone drew them freehand. Arrowheads are rough triangles, slightly lopsided. Arrows are light gray (#dee2e6) or match the border color of shapes they connect.
