/* ==========================================================================
   INDUSTRIES SUB-PAGES — SECTION 4: HOW VISCAP SUPPORTS THIS INDUSTRY
   10 designs — built on the HOME PAGE base, blue-cyan family
   ==========================================================================
   Preview-only. Namespaced .i4- / .i4vN-. Six support blocks, each with a
   doc-verbatim area list (6–10 areas) and a named service link into the
   live /services/ pages. Blocks 2 and 6 are DOUBLE-ROUTED — two links in
   one block is this section's worst case, and every layout must hold it.

   THE ROUTE DEVICE — .i4-svc is the one shared link treatment, restyled
   per context but never re-invented:
     base    inline text link, 14.5/700 blue-cyan, 15x13 chevron, 4px nudge,
             padded to a 44px tap box and pulled back so layout holds
     --ghost the dark-band form: outlined 44px button, hairline border,
             border lights to white on hover (the .btn-ghost logic)
     --box   the card-foot form: full-width row over a var(--c-line) top
             rule carrying the 48x48 arrow box (the .svc-cards--rows kit)
   Multiple routes sit in .i4-routes (wrapping flex), which is what absorbs
   the double-routed blocks in every layout.

   CONTRACT (index.html, blue-cyan): 4px radius (8px media), #c4c4c4 card
   borders, var(--c-line) rules, neutral shadows, .22s hover, gradient in
   numerals and thin rules only, dark hairlines rgba(255,255,255,.22),
   numerals on dark SOLID var(--fam-300).

   DESIGN 8 — HAIRLINE MATRIX
   The compact connector: 1px var(--c-line) gaps through white cells, no
   radius, no boxes — ruled paper. The 2px gradient rule under the head is
   the matrix's top edge (a second hairline read as an unfinished join).
   Six cells resolve 2-up at 561 and 3-up at 941 — even at every width.

   DESIGN 9 — MEDIA COLUMN + ROUTE ROWS
   The .glance geometry rotated (the s6v5 logic): the factory photo becomes
   a full-height column beside the six rows. Single-route rows are one big
   link with the 48x48 box; double-routed rows are plain rows carrying two
   .i4-svc links — two targets, so the row itself must not be a third.
   Media nudge held to ≥1340 where the gutter can afford it.
