Part of #3709

Ok, here we go with the first shots... Some introductory comments:

• I'm proposing a one-pager. All info about the conference would be in the same page. It may seem it's too much information, but I think given the user needs of browsing the info about a conference, it makes sense to have it all in the same page (if we don't like the idea of a one-pager, it would be easy to breake each section into its own page).
• We'd have a fixed sidebar, that would let you easily jump from one section to another (and since it's on the same page, it would be fast)
• In the header we point out the conference title, dates, city and main CTAs: register and programme.
• The first two blocks (intro + details) would support inline images, videos, etc.
• For entities, I'm proposing two different sizes for the logos (see both screens)
• For speakers:
  • also two options regarding size
  • when you hover one of them, you would get the extended info (bio, links, sessions...). In the future, we may have permalinks for speakers (don't know if that's the idea already)
• Programme: you can see how you'd browse between days, and if a session (really, a slot) is multitrack, to browse between tracks. Content and streaming sections might/should not appear until they have content.
• Permalinks for sessions: I'll design this although it's not for the MVP (as some other things in these designs!)
• Registration: I've asked a question here about it.

One-pager or not, we can open individual issues to discuss about details for each section.
