A conversation reads at reading size

[WaylandYang]

Two things on the Chat page.

The text was too small to read for long

Messages were text-body, 14/22. That is the right size for the rest of the
product — table cells, rail entries, panel fields, all of it scanned rather than
read. A chat transcript is the one surface here you actually read, in paragraphs,
for minutes at a time.

Both sides now use text-title, 16/24. That is a step the scale already has, so
no sixth size was invented; the type ladder stays five deep.

The bubble had a border

Everything on this screen that carries a border is something you can act on: the
composer, controls, cards. A sentence you already sent is not one of those, and
outlining it hints that it is still live. The 8% ground is enough to tell the two
roles apart, so the border goes and the ground stays.

Also

DESIGN.md's type table had drifted from the CSS: it listed text-body as 13/20
and text-title as 15/22, while the tokens have been 14/22 and 16/24. Corrected,
and the title row now records that chat reads at that step.

Checked

• pnpm build clean; style guard 46/46.
• In the browser, on a real conversation: the user bubble is 16px/24 with
  border-width: 0 and its rgba(255, 255, 255, 0.08) ground intact; the reply is
  16px/26. Both were 14px, and the bubble had a 1px outline.
