Dimming keyed on a 30-day window meant a quiet forum rendered almost entirely grey. Read-state replaces it: forum_read stores when an account last viewed a thread, and a thread is read only while its newest post is no newer than that view — so a reply re-brightens it with no flag to clear. Anonymous readers have no read-state and see every row at full ink.

Marking read is its own op, not a side effect of forum.get, so crawlers and API clients cannot spend a reader's unread state. Titles now take the accent colour on hover (gated on hover: hover) and on :active, so touch keeps the affordance. check-in: c8a93fda64 user: dmestas tags: trunk
