/* ============================================================
   PriceWatch NZ — design system v4 · AAA+++ STUDIO PREMIUM
   Mobile-first. Every breakpoint is min-width.

   IDENTITY B "Studio Instrument" REFERENCE STANDARD.
   Spec: _plans/AAA-PLUS-STUDIO-PREMIUM.md §2.2 / §2.2b / §3 / §4.
   This site is site-local (work order: SL) — apply.mjs never touches it — so
   the Identity B token diff is ported BY HAND from _shared/styles.css and the
   canonical token NAMES are declared here so the two files cannot drift. The
   site's own historical names (--r*, --e*) are kept as aliases pointing at the
   canonical tokens, which is why 246 product pages keep rendering unchanged.

   Elevation doctrine: exactly ONE lift shadow (--shadow), spent on the one
   object per page that asks for action (the price box). --shadow-lg is for
   popovers only. Dark mode has no decorative shadow at all — elevation there
   is a surface step plus a hairline.

   AAA+++ STUDIO PREMIUM — Identity B ("Studio Instrument") mechanics
   Spec: _plans/AAA-PLUS-STUDIO-PREMIUM.md §2.2, §3, §4.
   Ported by hand from _shared/styles.css (this site is site-local; apply.mjs
   does not reach it). Identity B has no serif, so its premium register is
   weight discipline (400/500/700) plus the mono voice on every dated figure.

   ONE DELIBERATE DEVIATION from the shared file: the shared mono-voice selector
   list includes `.spec`, but on PriceWatch `.spec` is the product SPECIFICATION
   TABLE (table.spec). Applying the mono register to it would shrink every spec
   sheet on 246 pages to .8125rem. The register is carried here by .mspec
   instead; every other class name matches the shared file exactly.
