Every header and top-bar button's title becomes a tip the shell shows the moment the pointer arrives (the browser's own waits a second and looks different everywhere); it moves from `title` to data-tip so the native one never appears, and a module that sets `title` again is picked up on the next hover. The shell's own labels are "Settings" and "Remove"; the top bar's are "Fullscreen", "Add tile", "Layouts", "Admin"; Slack, PCO Plan, ProdCom and Timers shorten theirs to match. A− / A+ are a drawn − and + in Slack, PCO Plan and ProdCom, sized like every other header icon. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

/* PCO Plan — client part.

The server part reads Planning Center and (optionally) follows the

streamed. What is shown is this tile's own choice (gear menu →
|

colors, item-note categories); the text size is the title bar's A− / A+

the connection settings. */
