/* --- Vertical rhythm between the blocks ---------------------------------
   The file stacks the screen's blocks on a fixed rhythm, and it is defined
   here once rather than inside each section: a section owns its own height,
   never the air around it.

   Read off the Main screen (1:3): the header's box ends at 111 and the first
   block starts at 180; every neighbouring pair of blocks sits 150 apart; the
   footer sits 100 below the last one.

   150 is only the Main screen's number. Services runs 150 · 100 · 0, How It
   Works runs 100 below its halfway point, and the gap under the header is a
   different number on every screen. So the default lives here and a block
   that departs from it writes its own value once, in the markup, as
   `style="--gap: 100px"` on the <section> — the measured Figma number, next
   to the block it belongs to, still not a margin the section sets on itself.

   The FAQ on Main carries `--gap: 0`: its full-width blue fill is meant to
   start exactly where the founder block above it ends.                      */

/* --- Below the 1200 floor ------------------------------------------------
   The design stops at 1200: below that there is no narrower composition to
   fall back to, and `min-width` on its own gave a horizontal scrollbar — the
   headline cut off the left edge, half the hero off the right. A window at
   900 is not a phone; it is a laptop or a half-screen window, and a page you
   have to scroll sideways to read is broken in the only sense that matters.

   So the page keeps its 1200 layout and is scaled down to fit the window.
   Everything stays in proportion and simply reads smaller. This is not a
   narrow layout and it is no substitute for one — it is what the site does
   until a narrow composition is drawn.

   The scale itself cannot be written here: `zoom` needs a plain ratio, and
   no CSS expression turns a viewport width into one — dividing 100vw by 1200
   yields a length, which `zoom` rejects. So it is set by the small inline
   script the build puts at the top of every <body>, and `zoom` rather than
   `transform: scale()` because a transform would make the pinned header and
   the scroll-to-top control position against the transformed box instead of
   the window, and both would come unstuck.                                 */

                     (Figma "Rectangle 13", 1440 x 61)
     2. the lines  — the page's own .gridlines component, drawn a second
                     time so the seven lines sit OVER the plate
     3. the logo and the menu

   Geometry: the seven lines and the seven menu cells are the same seven
   positions. They are read from --line-step in tokens.css and appear
   nowhere else, so the page's line layer and the header's cannot drift.

   Three of the five header variants in the set are 113 tall instead of 61:
   Services (966:7456), Results (521:2698) and About (521:3038). The extra
   52 is a second row of links that hangs under the item that owns it —
   All services / Discovery Sprint under Services, Author Stories / Free
   Resources under Results, Our Team & Story / FAQ / Contact under About.

   Each sub-item sits on the SAME seven positions as the bar above it, one
   gutter right of its line, and the group's plate covers only its own
   columns. The rest of the row is bare: the page shows through it, with
   the seven lines carried down across the full width (Figma "Group 75").

   The block is a child of the <li> that opens it, so :hover and
   :focus-within on that item are the entire interaction — no script, and
   the pointer can travel down into the row without losing the hover
   because it never leaves the <li>'s subtree.

   It is an OVERLAY, not flow: on Services the hero deliberately starts at
   110 and runs up behind the whole header. A page whose first block is
   meant to start below the open row writes that into its own --gap.     */
/* The row is a frame box, not a window-wide one: every piece inside it —
   plate, rule, line copy, labels — is placed from --line-step, and the line
   copy is now anchored to the macket's 1440 frame (base.css §4.0). If this
   row stayed window-wide the plate would sit at 12.5 % of the window while
   the lines sat on the frame, and above 1440 they would come apart. */

   the item is itself absolutely positioned, so a descendant would be laid
   out against that one narrow cell instead of across the header. :has()
   carries the relationship instead.

   Three states, in this order, and the order is the whole logic:

     1. a page that belongs to a group holds that group's row open;
     2. the moment the pointer or the caret lands on ANY opening item, every
        row closes — otherwise the page's own row and the hovered one draw
        on top of each other in the same 52px strip, which is what the
        header did on all seven section pages;
     3. the row belonging to what is actually being pointed at opens.

   Step 3 also keeps the row open while the pointer is inside it, so
   travelling down from the label into the links does not close it. */

   Full window width, 415 tall in the macket, Vista Blue 1. The fill is

   no lines inside the footer.

   Vertical rhythm, read off the macket (footer top = 0):

        83  hairline, full working area
        98  tagline          |  50   Company / Services / Contact headings
       134  social icons     |  98   first link of each column
       184  Barcelona office | 289   last link of the Services column
       339  hairline
       354  legal links and copyright
       415  foot

   The right-hand link block starts level with the logo, so the first

   Insights — the article template.
   Figma screens Blog_A1 407:1454 · Blog_A2 422:3560 · Blog_A3 424:4027 ·
   Blog_A4 428:4460 · Blog_A5 438:1934 · Blog_A6 438:2574.

   The six screens are the same five blocks in the same order, at the same
   widths, with the same rhythm. They differ only in what the body says, how
   many "Title + text" blocks it takes to say it, which photograph the hero
   carries and which two articles the related cards point at. So this file
   carries the whole layout and has no fragment of its own; each page lists
   it in `pages.json` beside its own `aN` and the shared `tail`.

     hero    Section 1       1440 x 1154–1284   --gap 150 (under the header)
     body    the Title+text  885 wide, tables    --gap  50
             column          1340 wide

   Inside the body every block is 50 from the next, which is the same 50 the
   body block sits below the hero; inside a block the rows are 25 apart.

   The whole file is one media query. Below 1024 this layer overrides the
   desktop layer; at 1024 and up not a single rule here applies, so the

   Why an overlay rather than two wrapped halves: the desktop CSS is live and

   a layout that is not changing. This way the desktop bytes stay as they are
   and the mobile layer states only its differences.
