   accelero.sh — product landing

   PALETTE SOURCE: img/android-chrome-512x512.png (the logo).
   Quantised the logo and it is TEAL/CYAN, not green:
     hue 180-199 = 43.5% of pixels, hue 200-219 = 16.8%,
     green (120-139) = 0.1%.
   Saturated logo pixels cluster #084860 / #105870 / #186078 /
   #207088 (deep teal); the porthole ring is hue-210 steel grey;
   the darkest hull tones are #081828 / #081820.

   Do NOT reintroduce the blog's green (#4ade80 / #22c55e). This
   site is intentionally NOT styled after arbianshkodra.com — that
   was a prior misstep. The blog is a personal reading surface;
   this is the product's own brand, taken from its own logo.

   Contrast verified against WCAG AA (see notes inline):
     #0e7490 on white  = 5.36:1  (text + primary button)
     #0891b2 on white  = 3.68:1  -> FAILS, decorative use only
     #22d3ee on #0b1620 = 10.11:1 (dark-mode accent)
