/* askaboutdomains.com — STYLESHEET
   Implements docs/design-spine.md, which is LOCKED. Every section below cites
   the spine section that authorises it. No framework, no reset library, no
   build step: this file is served as written.

   The formal grammar is inherited from C:\github\cars (radius 0, 2px hard
   rules, 4px 4px 0 hard shadow, hard-stop patterns only, 100-150ms linear or
   steps motion). The one deliberate break: body prose is a serif at 19px/1.65
   inside a 68ch measure, because this site is read, not operated. */
