   --------------------------------------------------------------------------
   Purpose
   - Weighted field for tier resolution.
   - Four dimensions resolve to a service tier via a scoring formula.
   - Mirrors the boonhonk-mixer interaction language, but with more explicit
     dimensional hierarchy, value reasoning, and SVG-ready semantic states.

   Design goals
   - Prepare for more advanced combinatorics and SVG interactions.
   - Make price movement, charge, and utility feel grounded and legible.
   - Support elegant, screenshot-worthy value selection with precise state.
   - Give JS a richer state grammar without forcing immediate HTML changes.

   Suggested JS-facing attributes / classes
   - [data-svc-state="idle|probing|weighted|resolved|projecting|comparing"]
   - [data-svc-focus="time|scope|depth|tenure|center"]
   - [data-svc-tier="fast|standard|premium|blended"]
   - [data-svc-utility="low|medium|high|magnified"]
   - [data-svc-charge="0..1"] or inline custom property --svc-charge
   - [data-svc-price-shift="stable|rising|falling|floating"]
   - [data-svc-axis-state="quiet|active|locked"]
   - [data-svc-combinatorics="simple|layered|advanced"]
