fix(tokens): correct raised surface level, on-inverse text, shadow glow, space-scale integration; clarify cq breakpoint tokens

[jackgranatowski]

• --sf-color-raised: l+0.02 → l+0.04 so hierarchy well < surface < bg < raised is correct
• --sf-color-text--on-inverse: var(--sf-color-text) → var(--sf-color-text--inverse) — dark text on dark inverse surface was unreadable in light mode
• --sf-shadow-glow: replace color-mix(calc%) with oklch relative color syntax — calc() inside color-mix() percentage is not guaranteed by spec across browsers
• --sf-space-*: wrap fluid clamp() in calc(... * var(--sf-space-scale)) — makes space-scale a working multiplier like radius-scale and motion-scale
• --sf-cq-*: add comment explaining custom properties cannot be used in @container/@media queries; values are JS-readable reference constants

Summary by CodeRabbit

• Style

  • Updated design tokens: adjusted raised surface color, on-inverse text color, refined shadow glow (including alpha computation), and made spacing tokens fluid via the spacing scale for improved color consistency, surface rendering, and layout flexibility.

• Documentation

  • Removed container-query breakpoint variables and clarified container query usage and recommended approaches.

📝 Walkthrough

Walkthrough

Updated core/tokens.css: color tokens (--sf-color-raised, --sf-color-text--on-inverse, --sf-shadow-glow) changed their computations; fluid spacing tokens now multiply their clamp() results by var(--sf-space-scale); container query breakpoint custom properties were removed.
