/* ============================================================================
   SL LOOP KIT
   ----------------------------------------------------------------------------
   ONE CLOCK. Every animated element shares --lc and carries NO animation-delay.
   Staggering lives inside each keyframe as a percentage offset. This is exactly
   what the live blog CTA does (.loop .step.k1..k6, 8.4s linear infinite, offsets
   at 0 / 16.67 / 33.33 / 50 / 66.67 / 83.33 per cent) and it is why that one
   reads as assured. Per-element animation-delay on an infinite animation puts
   every element on its own clock, so nothing rests together and nothing resets
   together. That was the mechanical cause of "a bit unprofessional".

   SECOND RULE: the loop moves ATTENTION, it does not conjure objects. Anything
   that should be readable in a still frame is present from frame one. Things
   only assemble where the assembly IS the idea (blocks locking, a route being
   planned, an organiser changing shape).

     No red (Paul, 23 Sep). Literals on purpose. Curve-fitting them from framework tokens would tie a block to unrelated

     WHITE, not light blue (Paul, 24 Sep: "the real product is purple, yellow, green and white; there are no light
     blue blocks"). The white frame is a neutral derived from tokens, not a literal: a white block is the colour of

/* ===== What is it for? v10 (25 Sep): the flow, left to right. IDEAS IN (a slide; its three phrases are pulled out as blocks),
   TALK (the blocks put in order), IDEAS OUT (the sentence written). Live text. The kit colours fill only the blocks and the
   marker under the three phrases, because the drawing is OF the blocks; everything else is ink, neutrals and the one teal.
   Motion: every animation runs on --cf-clock, staggered by keyframe percentages, never a delay. Frame 0 (and the base
   styles) is the finished drawing, so reduced motion needs only animation:none. Timeline, as percentages of the clock:
     0-4 finished, at rest       4-8 everything but the slide fades (the reset)
     10-29 IDEAS IN: each phrase is marked, then its block drops out of the slide (plates, pressure, rocks)
     30-34 first arrow nudges    34-54 TALK: blocks appear jumbled, "What comes first?", two swap, "The plates move!"
     55-59 second arrow nudges   60-81 IDEAS OUT: the three lines are written    81-100 finished, at rest ===== */

/* ===== shared platform band =====
   A filled band in the page's own colour, set by data-domain (the page's {{DOMAIN}}): map = --sl-map-text, say = --sl-say-text,
   build and brand = --sl-brand-hover. Any other value falls back to brand. White body text on each fill, measured 23 Sep 2026:
   map-text 5.50:1, say-text 6.16:1, brand-hover 6.44:1, all past AA 4.5. The *-text tokens are the fills because the base
   domain colours fail white text (map 3.17:1, say 4.17:1, brand 4.44:1). The button hover (fill on its wash) is 4.80:1 at worst. Colour rules carry #platform so a page's own .accent,
   .eyebrow or .btn-primary rules cannot repaint the band. The button is white, the lightest thing on the band.
   The illustration uses one colour family (the fill and its wash) plus white and ink. Everything below is styled as the
   FINISHED frame; platformband.js animates from it, so without JS, or under reduced motion, the finished frame shows. */

   orange, build and tf teal, none brand teal): --mk for the page's own filled dot, --acc for type (the *-text token, because
