   Altamonte HVAC — altamontehvac.com
   Direction: compact utilitarian. Signage logic, high information density.

   Rules of this system, so later edits do not soften it:
   - Everything is a rectangle butted against another rectangle. No radii
     above 2px, no drop shadows, no gradients on content.
   - One hairline weight (--line). Panels share edges; they do not float.
   - Micro-labels are uppercase, letterspaced, and always name the source or
     the section number. That is the signage voice.
   - Numbers are tabular everywhere. The site is an argument made of figures.
   - The condo / house split is the spine: .split, .side--a (attached) and
     .side--d (detached) recur on every page and must keep their edge colours.
