/* Zypa Finance — preview v18 shared styles (home + assessment).

   Direction: Apple product-page style, measured from apple.com, /apple-card
   and /apple-pay (1440px viewport, computed styles):
   - Type: the Apple system font (SF Pro) wherever the device has it, via
     -apple-system / BlinkMacSystemFont. SF Pro may not be embedded as a web
     font (licence: UI mock-ups for Apple platforms only), so other devices
     get Inter with optical sizing, the closest open match.
   - Apple's scale and tracking: body 17/25 at -0.022em; 21px intros at
     +0.011em; 24–32px titles slightly open; 56px headlines at -0.005em;
     80–96px heroes at -0.015em. Weight 600 for headlines, 400 for buttons.
   - Neutrals: #1D1D1F ink, #6E6E73 secondary, #D2D2D7 hairlines, #F5F5F7
     light sections. Zypa jade replaces Apple's blue for links and buttons.
   - Pills (980px radius) for buttons, 44px tall; 18–28px radius on tiles;
     52px frosted local nav with 12px links.
   - Colour like Apple: neutrals do the work (white, #F5F5F7, black for the
     one dark section); a single accent (Zypa jade, in Apple's blue role) for
     buttons, links and "matched" states — brighter on dark backgrounds.
   - Motion like Apple (values from their stylesheets): UI changes 240–320ms
     on cubic-bezier(.4,0,.6,1); reveals 0.8–1s on cubic-bezier(.25,.1,.3,1),
     opacity + 40px rise, no blur. */
