/* ==========================================================================
   PolarLabs — Why PolarLabs page (/why-polarlabs/)
   Route-scoped: enqueued only on this page (inc/why-polarlabs.php) and every selector sits under
   .pl-whyp (NOT .pl-why, which main.css already uses for the homepage section). Built only on the
   global --pl-* tokens (translucent tints are color-mix() of tokens) and the global primitives
   (.pl-container, .pl-sectionhead, .pl-btn, .pl-prose, .pl-breadcrumb).

   Direction: scientific-editorial. A navy masthead with one CSS-only polar reticle (the V5 "Reticle"
   identity), large tight Manrope heads under the site's line kicker ("— KICKER", as on Support), Inter
   body on a generous measure, hairline matrices, one card anatomy for the standards, a two-pane founder
   note, a records ledger for the documentation status, a calm research-use panel, a business-card
   company card, a ruled FAQ and a navy closing card that echoes the reticle.
   Status colour appears ONLY on the ledger pills: Published = info blue, Pending = pending amber
   (never success green); On request = neutral grey.
   The template renders the sections in the copy map's order and alternates white / frost backgrounds
   in render order (.pl-whyp__section--frost), so no rule depends on section order.

   OWNER DECISION (flagged): the navy masthead departs from the light inner-page heroes. The hero
   surface is ONE knob (--whyp-hero-bg); its text tokens sit right beside it (--whyp-hero-*).

   Sections: 0) Knobs + shell  1) Section heads + split layout  2) Hero  3) Market  4) Standards
   5) Founder note  6) Documentation + ledger  7) Research use  8) Company  9) FAQ  10) Closing CTA
   11) Tablet  12) Phone (<=640)  13) Small phone (<=380)  14) Reduced motion
