   DOELVE — THE SPECIFICATION SHEET
   Hand-written. No preprocessor, no build step, no @import.

   TWO TIERS, ENFORCED:
     --p-*      primitives. Raw values. NEVER referenced by a
                component rule. Never redefined in a media query.
     --color-*  semantics. The only colour tokens a component
                may reference. The dark block redefines ONLY
                this tier.

   Light is canonical: this is a paper document. Dark is a
   deliberate NEGATIVE PRINT, not a dimmed clone.

   Every ratio in a comment below was computed against the exact
   hex pair named. Change a value, recompute the comment.

   yields a complete page, never a blank one.
