/* ─────────────────────────────────────────────────────────────────────────
   WUR motion layer.

   Ported from the pixel-level teardown of wur.nl/en (2026-08-24):
     1. pill button   — spring(300, 30, mass 1) scale 1.02 + shadow, colour
                        on a separate 250ms cubic-bezier(.87,0,.13,1) track
     2. card hover    — scale on a layer OUTSIDE the card, 300ms ease,
                        centre origin, z-index 2 → 3, no neighbour reflow
     3. photo morph   — one SVG <image> under a mask whose path morphs on a
                        spring(280, 60, mass 1)

   The spring halves live in motion.js; this file is the CSS half.
   Geometry only ever animates through `transform`, never width/height/
   padding, so nothing on the page re-lays-out on hover.

/* ── 1. Pill button ─────────────────────────────────────────────────────
   Colour, background and border transition on their own 250ms track.
   scale and box-shadow are driven imperatively by the spring in motion.js
   and are deliberately absent from `transition` here — a CSS duration
   would fight the integrator and kill the carry-over of velocity that
   makes a fast in-and-out feel continuous. */

/* ── 2. Card hover ──────────────────────────────────────────────────────
   The teardown's finding is that the transform belongs on a layer OUTSIDE
   the card, never on the card's own box and never on the image inside it:
   everything the card contains then scales as one piece, and because it is
   a transform the neighbouring cards never re-lay-out.

   Amplitude, easing and origin are the measured ones: scale(1.05) over
   300ms on the browser's default `ease`. These rows are full-bleed inside
   a clamp(24px, 5vw, 64px) gutter, so the 2.5% each side has room to grow
   into up to roughly a 2560px viewport; past that the gutter stops being
   wide enough and the growth would reach the screen edge. */

/* ── 3. Project photos ─────────────────────────────────────────────────
   Three tiles in one row inside the project modal. Each is an SVG <image>
   under its own mask, so a photo reads as an organic shape rather than a
   rectangle; hovering springs that outline to a different shape while the
   tile itself takes the card treatment from §2 above — scale on a layer
   outside the artwork, 300ms ease, centre origin, z-index lift. Clicking
   opens the photo full size.

   The 30% offset-follow from the source teardown belonged to its one-image
   layout and has no counterpart here: with all three visible at once there
   is nothing for a single canvas to track. */
