SVG Architectural Elevation Drawing

Core aesthetic: CAD-level precision in proportions and geometry, rendered with the warmth of a ballpoint pen sketch on paper. This is not a tension to resolve — it IS the skill.

The result must feel trustworthy (correct proportions, buildable), personal (human line quality), inviting (life elements, context), and not surreal (no floating parts, no impossible geometry).

Mental test: imagine the drawing printed on cream paper and pinned to a corkboard in a café. IKEA instruction → too clean. Napkin doodle → too rough. Aim for: "someone who can draw lovingly drew this careful thing."

Phase 0: Decisions (MANDATORY — write as SVG comments before any element)

Skipping this is the #1 reason drawings look generic. Declare ALL five before writing <svg>:
