   TECH 52 LIMITED — tech52.org
   Company No. 17047936 · England and Wales
   SIC 63120 (web portals) · 62020 (IT consultancy) · 73110 (advertising)

   Design direction — "the masthead".
   A portal is a publication that happens to be software, and this company
   builds portals, advises on them, and buys the audience for them. So the
   site is built like a printed title rather than a product page: a warm
   obsidian ground (ink, not black), a high-contrast didone display face,
   numbered sections in mono, hairline rules instead of shadows, square
   corners, and exactly one accent — carnelian, the colour of a printer's
   red plate — used as a line, a numeral and a mark, never as a fill.

   Two devices carry the name: the 52-tick rule (fifty-two hairlines, every
   thirteenth accented — the weeks of a publishing year) and the numeral 52
   set as a masthead folio. Occasional bone-paper bands invert the page, as
   if a printed sheet had been laid on the desk.

   Structure: tokens → reset → layout → components → pages → responsive.
   One stylesheet. No build step, no framework.
