Controller ee(e) is the page-swap routine (called by an Astro router caller in module 4533a63d3ea2bdc80f5c0e842466c14f:1 at node 8a11504bbcd3e4373509:2026:2046) that replaces the document with a newly fetched document e. In order: W marks scripts already executed (skipping data-astro-rerun and scripts seen before via M); V copies new html attributes onto document.documentElement, retaining only U=[data-astro-transition, data-astro-transition-fallback] from the old element; K synchronizes head children, removing old head elements unless a matching persisted/stylesheet/style/font counterpart exists in the new head (J), then appends remaining new head children; G captures the active element (and input selection) if it lies inside a [data-astro-transition-persist] subtree and returns a restore closure; z swaps body: each persisted old element in document.body is matched to the new body element with the same persist value, moved aside (moveBefore on documentElement when available, else appendChild), document.body is replaced by the new body, then each old persisted element is moved into the placeholder position and the placeholder removed; astro-island elements whose props changed (Q and Z) get ssr/props updated; N attaches declarative shadow roots in the new body. Finally the G restore closure (E) refocuses the captured element and restores selectionStart/selectionEnd. For this controller the persisted element is header#site-header with data-astro-transition-persist="astro-exhj5wib-2" (desktop and tablet samples); it has no controls and no own animation in the packet. Effect: the same header DOM node survives navigation rather than being rebuilt.

Targets: [data-astro-transition-persist], [id="site-header"]

• The persist key is the constant data-astro-transition-persist (T); the header value is astro-exhj5wib-2 in recorded desktop and tablet samples. Matching is by exact attribute value between old and new body.
• Element move uses documentElement.moveBefore when it is a function (keeps focus/state), otherwise appendChild / replaceWith. Which branch runs depends on browser capability; not established per profile.
• Focus restore is armed only when document.activeElement is inside a [data-astro-transition-persist] subtree (closest). Input/textarea also restore selectionStart and selectionEnd when numeric. Focus elsewhere is ignored.
• Each current head child is matched by J: persist value in new head; stylesheet link by href; style by identical textContent; preload font link by href. A match removes the NEW head element (old kept); no match removes the OLD element. Remaining new head children are then appended.
• Scripts in the new document get dataset.astroExec='' unless they carry data-astro-rerun or M reports their src/text as already seen (set L). This is a dataset flag only in this controller.

Module code in b27a3aa4e2b0ad7299af926277bdd68e:0 looks up #site-nav-dialog and .page-wipe. If the dialog exists and contains a ul, C(dialog) builds a controller that splits each list link into masked lines, animates them in on open and out on close, and treats plain link clicks as pending navigations. If the page-wipe exists, W(controller, M(wipe)) hooks Astro router events so an anchor navigation covers the page with the wipe, restores the open dialog for the swap, animates items and wipe out, then resets. Reduced motion (p()) bypasses tweens and uses immediate popover show or hide. Source-only; execution not confirmed.

Targets: [id="site-nav-dialog"], .page-wipe, [id="site-nav-dialog"] ul a

• Module constants: m=0.5, delay=m*0.55 (0.275 s), b=0.15. Item-out uses delay+m; wipe timing uses delay+m and b.
• C(e) returns null unless e.querySelector('ul') exists, so no dialog listeners attach when the list is absent.
• L() reverts previous splits via g(), then creates a lines split of each link (c_1.create, type lines, mask lines) and stores flattened lines in n.lines.
• p() from the motion module gates items-out and open/close: when true, tweens are skipped and popover show/hide and style sets happen immediately.
• beforetoggle listener: when not pending and newState==='open', kills tween a, sets link autoAlpha 0, and sets inert=true on body children other than #site-header.
• beforetoggle close path: inert cleared; if reduced motion, f() resets and returns; otherwise playItemsOut() and a delayedCall(delay+m) that runs f() if the popover is no longer open.
• Click on an anchor inside the dialog ul without href, or with meta/ctrl/shift/alt or target _blank, is ignored; otherwise preventDefault, pending=true, and router navigate n_1(href).
• astro:before-preparation returns early unless event is router T, controller not pending, navigationType not traverse, sourceElement is HTMLAnchorElement, and not reduced motion. Otherwise sets flag n, calls wipe cover(), and wraps loader to await loader and cover promise.
• astro:before-swap kills all S_1.getAll() ScrollTriggers.
• astro:after-swap: drops the cover if started; if controller pending, restore() (showPopover without transition), h(), awaits playItemsOut and playWipeOut, calls r_1(), reset() and S_1.refresh().
• reset() sets pending=false and runs f(), which kills tween a, reverts splits, and clears opacity/visibility/transform on links.

Module 52a0ef3fcf041e20edb6810ecd10a431:0 registers a document astro:before-swap listener that removes is-over-cta from #site-header, then at module load calls b(".cta"). b(a) defers work through imported helper o(...), reads #site-header once, and for each .cta element: (1) returns if dataset.ctaRevealDone is already set, otherwise sets it to "1"; (2) if the header exists and dataset.ink !== "light", creates a ScrollTrigger (S.create) whose start/end are functions resolving to "bottom bottom+=H" / "bottom bottom-=H" with H = header offsetHeight, toggling is-over-cta on the header with isActive; (3) if imported guard p() is truthy, returns before any timeline; (4) otherwise, if both .cta__fixed and .cta__stage exist, builds a scrubbed (scrub:1) GSAP timeline from top bottom to bottom bottom animating the stage from opacity 0, scale a_1, brightness(R) to opacity 1, scale 1, brightness(1), and the fixed layer from blur(b_1 px) to blur(0px), both ease none at position 0. Imported symbols o, S, p, g, R, a_1, b_1 are unresolved in this module and must be resolved from motion.Bn59Lf8D.js.

Targets: [id="site-header"], .cta, .cta__fixed, .cta__stage

• On document astro:before-swap, the listener removes class is-over-cta from #site-header (optional-chained, so no-op if absent).
• Module evaluation calls b(".cta") once at top level; there is no other caller in this module.
• Setup body runs inside o(() => {...}); o is an imported helper from motion.Bn59Lf8D.js whose semantics (ready/readiness/deferral) are not yet resolved.
• Header ScrollTrigger is created only when the #site-header element exists and trigger.dataset.ink !== "light".
• After the header trigger, if p() is truthy the callback returns before the stage/fixed timeline is built; p is an imported guard whose meaning (likely reduced motion) is unresolved.
• Timeline is built only when both .cta__fixed (variable o) and .cta__stage (variable r) are non-null.

Function k(e) runs for the page header h1 only on the non-reduced branch of z (the else-if branch when the flag c is falsy). It waits for document.fonts.ready or a 500 ms timeout, splits the h1 into lines (type "lines", aria "auto"), creates a fromTo tween on the lines (opacity 0 to 1, y 0.08em to 0, blur 8px to 0px, duration 2.4, stagger 0.12, delay 0.1, ease expo.out), sets the h1 autoAlpha to 1, records window.innerWidth, and registers a resize listener. A width change (height-only changes ignored) completes the tween with progress(1) and runs cleanup (remove listener and revert split). Tween completion also runs cleanup. Returns a promise resolved by delayedCall at f + duration - m*(1-C), which z races into its intro readiness chain before calling h.

Targets:

• k first awaits Promise.race of document.fonts.ready and a window.setTimeout resolve after $ (500) ms; the split and tween only start after whichever settles first.
• window.innerWidth is captured after the tween and set; a resize listener o is then registered. o compares the current innerWidth with the captured value; only a width difference triggers action. Height-only resizes do not match this guard.
• On a width change, o calls n.progress(1) (jumps the line tween to its end) and then i() (removes the resize listener and reverts the split).
• i removes the resize listener with the same handler reference o and calls t.revert() to undo the line split.
• n.then(i) runs the same cleanup (remove resize listener, revert split) when the line tween completes, so the split does not persist after the intro.
• z calls k(t) only in the else-if branch when the h1 exists and the flag c is falsy; when c is truthy z instead sets autoAlpha 1 on the h1 and does not run k. z returns early if trigger.dataset.introPlayed is already set. The identity of c (p_1 import) is unresolved in the package.

Root callback at input.js line 214 (node 4afa0c09836bd3752af8:5538:5611) runs document.querySelectorAll(".page-header").forEach(z). z (node 4afa0c09836bd3752af8:1045:4538) is the per-header intro: it returns immediately when trigger.dataset.introPlayed is set, otherwise sets it to "1" and gathers h1, .page-header__crumbs, .page-header__fixed, .page-header__stage, .page-header__media, mux-player or img.page-header__asset, [data-play-pause]. It derives compact/cropped flags and a halftone flag; c=p_1() is an unresolved reduced-motion/flag import. If mux-player exists it preloads the player and wires play/pause (b_2). Media ready promise I is V(img) (image load/error or 4000ms timeout) or the video gate w(). It awaits w_1 (header-intro-gate import), fades the crumbs in, and either sets the title visible (c true) or runs k(title) (split line reveal). Promise.all([I,p]).then(h) runs h: in reduced branch (c) sets media/play button autoAlpha 1 only; otherwise fades media, scales poster/asset from U=1.08 to 1 over W=3.2s expo.out, blurs from B=20px to 0 over F=1.5s, and fades the play button over 1s after delay=0.8. Finally, unless c or g (compact/cropped) or missing d/i, a scrubbed GSAP timeline on the header (start top top, end bottom top, scrub 1) scales the stage to a (unresolved import) and brightness R, and blurs the fixed layer to b px.

Targets: .page-header, [data-intro-played], .page-header__media, img.page-header__asset, mux-player, [data-play-pause], .page-header__stage, .page-header__fixed, h1, .page-header__crumbs

• The root callback at line 214 queries every .page-header in the document and calls z on each (no per-element guard at this level).
• z returns immediately if trigger.dataset.introPlayed is truthy; otherwise it sets introPlayed='1' before any animation, so a header runs its intro at most once per document.
• If an h1 exists and c is falsy, z awaits k(h1) (split-line reveal). If c is truthy it sets the h1 autoAlpha 1 directly. If h1 is absent, no title step runs.
• If an img.page-header__asset exists, the ready promise is V(img): resolves immediately when complete with naturalWidth>0, else on load or error or after 4000ms. Otherwise the ready promise is w(): resolves immediately if no mux-player or if c is set; else resolves via customElements or a race of the player's playing event/4000ms plus play().
• c = p_1() is an unresolved import (motion module). When c is truthy the h callback only sets autoAlpha 1 on media/play button, with no tweens; title is set visible without split reveal; crumb fade duration is 0. Its meaning (reduced motion) is not established from source alone.
• The scrubbed timeline is created only when !(c || g || !d || !i), where g = header has page-header--compact or page-header--cropped, d = .page-header__fixed, i = .page-header__stage. The poster/asset scale and blur tweens run only when media exists and S (not cropped and no .halftone inside media).
• In k, a resize handler o (registered on window) compares window.innerWidth to the width captured at split time; if changed it calls n.progress(1) and i(). i() removes the resize listener and calls split.revert(). n.then(i) also runs cleanup when the split tween completes, so the resize listener is removed after the reveal.

Function C(e) binds to a popover element e that contains a ul. If no ul exists it returns null. It keeps a pending flag n.pending, split-line handles n.lines and a delayed-close timer a. On beforetoggle it either (open) kills the timer, hides the links with autoAlpha 0 and marks body siblings inert, or (close) makes siblings non-inert, then either resets immediately under reduced motion (p()) or plays the line slide-out and schedules f() after delay+m. On toggle-open it either sets links visible under reduced motion, or in requestAnimationFrame re-checks :popover-open, splits the links into lines with c_1.create, and slides the lines in with g_1.from. Clicking an eligible link in the ul sets pending and calls router navigate n_1(href). The returned API exposes isPending, restore, playItemsOut, playWipeOut (clip-path wipe then hidePopover and r_1 gate), and reset (clears pending and calls f()). Constants: m=0.5, delay=m*0.55=0.275, b=0.15.

Targets: ul, :scope > :not(#site-header)

• C returns null when e.querySelector("ul") is falsy. Otherwise it registers beforetoggle, toggle, and ul click listeners and returns the controller API.
• The only recovered caller is C(P) inside a guard on P &&. P's selector and the first-visit condition are not resolved in this pass, so activation is omitted.
• beforetoggle with newState not open and no pending: sets siblings inert false. If the reduced-motion predicate p() is truthy, calls f() and returns. Otherwise calls playItemsOut() and schedules a delayedCall at delay+m that sets a=null and calls f() when l() (popover-open) is false.
• toggle with newState open and no pending: if p() is truthy, sets links autoAlpha 1 and returns. Otherwise, in requestAnimationFrame, returns if !l(); otherwise L() splits the links with c_1.create type lines and mask lines, sets autoAlpha 1, then calls g_1.from(lines, yPercent 110, duration 0.6, ease power3.out, stagger 0.07, delay).
• Click on an anchor within ul with href, no meta/ctrl/shift/alt modifier and target not _blank: preventDefault, pending=true, router navigate n_1(href). Otherwise the default is left alone.
• f() kills timer a, sets a=null, calls g() which kills line tweens, reverts the split instances, and clears s and n.lines, then clears opacity,visibility,transform on the ul links. reset() sets pending=false and calls f().
