Subject: Posts and messages get a reading size.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A feed of posts was set in .small — 13px, the size used for captions and
row subtitles. On a phone it read like footnotes. Measured against
Amethyst on the same Pixel 9, side by side: its note body renders a line
pitch of 62 device pixels, ours 50.

Post bodies get their own class at 16px, which is Amethyst's own default
for a note body, and chat and DM bubbles move 15 → 16 to match; the names
and inbox previews above them keep pace. New line pitch measured on the
phone: 60 against Amethyst's 62. A quoted note inside a post stays a step
smaller, since it's context rather than the post you're reading.

Worth recording for whoever reads this next: this phone has the Android
font scale at 1.15. Amethyst uses sp and honours that automatically; CSS
px in a TWA does not, and there's no way for a page to read that setting.
So Amethyst will still render about 15% larger than us on this device no
matter what we pick. Matching its DEFAULT is the target that makes sense
for everyone else.

chat-layout-test had rotted (onboarding copy, .header-msgs now matching
the settings button, a screenshot path from another machine's scratch
dir) — repaired, and it's what proves the composer still fits at the
larger size, on all three viewports.
