   #s4 SERVICES — "The tools to actually run the place"  (CENTREPIECE)
   Layout archetype: FULL-BLEED device with the copy CENTERED ABOVE it.
   Deliberately distinct from neighbours: s1 full-bleed hero (laptop lid),
   s2 centered five-to-one converge, s3 split copy-left/device-right morph,
   and s5 (next) will be split device-LEFT. This section is the only one where
   the device sits wide and alone below a centered text block.

   Signature motion (ONE): the Fellside Pantry ops dashboard COMES ALIVE as the
   section scrolls through. A single scrubbed proxy (--life 0 -> 1) orchestrates
   the whole screen: KPI numbers count up, the 7-day takings line path-draws and
   its area fills, the top-seller bars grow, and the busiest-day cell ignites
   gold last. It reads as one staged "the place waking up" gesture, not a pile
   of separate tweens. This is the richest single animation on the page; no
   device rotation here on purpose, so all attention is on the data coming to
   life. Everything animated is transform / opacity / stroke-dashoffset only.

   Reduced motion / no-JS: the dashboard rests fully ALIVE (all figures at final
   values, line drawn, bars full, busiest cell already gold). Nothing hidden.

   THE GREENSLATE KITCHEN OPS DASHBOARD  (LIGHT BRAND: .mb mb--greenslate)
   ----------------------------------------------------------------------------
   The screen is its own light/modern bistro product UI (sage + cream + brass),
   NOT the Beaufort-dark chrome. All colour comes from the shared mock-brand kit
   vars (--mb-*), never the dark tokens. The ANIMATION HOOKS are untouched: every
   class still derives its motion from the single --life 0..1 proxy exactly as
   before (count-ups via [data-count], line path-draw via --len/--life, area +
   dots fade, top-dish bars grow via --v + --life, busiest cell ignites LAST).
   Only the palette/typography are rebranded. A full ops surface: header strip,
   4 KPI cards, a tall 7-day takings chart with the busiest-day cell, top-dishes,
   hours-by-day mini grid, and the alerts rail.
