YUNUS EMRE VURGUN — "JELLY" BRAND LAYER
===============================================================================
Loaded after ui-rebuild.css (which owns structure, grids and responsive
behaviour) and variables.css (which owns every token). This file owns the
brand's look:

  · the page is the mascot's own light-blue sky; content sits on cream, like
    the crown of the mascot's cap; ink is the cap's navy; red is the jelly.
  · the shape language is the gelatine mould: chunky radii, lobed (scalloped)
    edges where a section meets the page, a bright top edge on every surface.
  · motion is the jelly spring — press squashes, release overshoots — and it
    exists only where something is pressable or the mascot is. Everything
    reads fully with animation disabled.

Never hard-code a colour here: consume the tokens in variables.css.
