   mechanism-card-v2 — additive variants for the /technology page (§4 §2).
   Date: 2026-05-03 · Project: WebShield technology — IP-architecture spine v2.

   ── LOCKED VARIANT ──────────────────────────────────────────────────
   Step 1 of /technology is LOCKED on  .ws-mc--substrate-coderef
   (Variant C-refined · "Compiled definition, pushed colder").

   Selection rationale (carried into deviation log):
     • This page diverges from the homepage's serif-led card register
       on purpose. The /technology audience #1 (per brief §1.1) is IP
       counsel performing FTO analysis. They read claim charts, not
       editorial cards. C-refined matches that mental model:
         §4.X.Y · MECHANISM · Claim N · §K  spec breadcrumb,
         FUNCTION: / DEPLOYS:                labeled spec rows,
         PRIMITIVES · N                      counted manifest as
                                              the visual centre of gravity.
     • Rhythm-test gating criterion: substrate must read as a
       categorically different object from the Universal Cards (.ws-uc)
       two scrolls below. Variants A and B failed this test at canvas
       zoom; C-refined passes.
     • Reuse footprint is system-wide, not bespoke to §4.2: the
       FUNCTION/DEPLOYS ledger and §X.Y · KIND breadcrumb extend to
       §3d composed-services, §3a layer headers, and any future
       claim-chart pattern on /patents.

   ── ADDITIVE, NOT SUPERSEDING ───────────────────────────────────────
   The locked v1.3 mechanism-card.css remains untouched. The /patents
   page continues to render .ws-mc with its Supports→universal-chip
   footer. /technology renders .ws-mc + .ws-mc--substrate-coderef on
   top, overriding only the slots that differ. Resolves §8.2 J-2.

     .ws-mc--substrate-spec      Variant A · Spec-sheet
                                  EXPLORED, NOT CHOSEN — did not pass
                                  rhythm test (read as "more cards" at
                                  canvas zoom against Universal Cards).
                                  Preserved for handoff iteration history.
     .ws-mc--substrate-ledger    Variant B · Claim ledger
                                  EXPLORED, NOT CHOSEN — did not pass
                                  rhythm test; header strip pattern had
                                  no reuse beyond §4.2.
     .ws-mc--substrate-code      Variant C · Compiled definition
                                  EXPLORED, NOT CHOSEN — superseded by
                                  C-refined; kept as comparison base.
     .ws-mc--substrate-coderef   Variant C-refined · LOCKED for Step 1.

   All variants:
     • Source color, type, spacing, rule weights from webshield-navy.css.
     • Add NO new tokens.
     • Are visibly tighter and more technical than .ws-uc.
     • Override only the slots that differ from the v1.3 patents-page shape.

   Internal slots:
     .ws-mc__role         one-line italic role (A/B/C)
     .ws-mc__primitives   primitive-manifest container
     .ws-mc__primitive    one primitive item
     .ws-mc__xref         deep-technical-block cross-reference
     .ws-mc__spec-header  mono spec breadcrumb (C-refined only)
     .ws-mc__spec-list    labeled FUNCTION/DEPLOYS rows (C-refined only)
     .ws-mc__name--cold   sans-500 + code chip name (C-refined only)
