* Added replacement svg assets, deleted ones we will no longer use * Create technology.png * introduction layout complete * + add gray backgrounds to <pre> code for legibility * adding pictures and text * spacing changes * add images * reference newly added images * using docs master * updated svgs * refactoring the naming scheme for svgs * replacing archive .svg * normalized image sizing per the design (50% text, 50% figures), removed sidebar nav * Fixed paged header styling, removed large type/thin weight * Removing the 30em max width on essays, additional info in description I noticed that the essay content for Understanding Urbit had a noticeably smaller max width than what we were displaying in "Understanding Urbit: Introduction", and saw that essay-wide, across the entire site, all non-image non-figure <article> widths were constrained to 30em max width, which is contrary to the original intent of the design — Essentially, the baseline rule is that ALL (and I mean, literallyl, all) primary body content on any given page should occupy the middle 6 columns (on a large enough viewport), regardless of where they appear. This means text, no matter which page it appears on, should always be set to occupy these columns at any given time no matter what content is displayed alongside the text. I get the sense this removal of the 30em max width might break some other pages, which might suck but is neccesary so that pages retain this strong uniformity throughout the docs + homepages * Accepting current change to render both Roadmap and History diagrams. * mobile layout and responsive spacing
