PR #392 moved the slug below the tab strip but kept it INSIDE the
sticky chrome — Mara's report ("still at old position everywhere
except flow tab") makes the original intent clearer: the slug
should be at the page BOTTOM, with the chrome reduced to pure
navigation.
## index.html
- Remove the banner-thin from `.dashboard-chrome` entirely.
- Move it into the existing `<footer>` element (above the divider
+ project-link line). Sits at the bottom of every tab pane after
the main content scrolls past.
## flow.html
- Remove the banner-thin from the chrome. The flow page is a
full-viewport terminal with `body { overflow: hidden }` and
no normal-flow footer position — the slug simply doesn't appear
here. The frosted chrome is purely the tab strip now.
## dashboard.css
- `--flow-header-h: 4.7em → 3.6em` — chrome is shorter without
the banner; terminal padding-top + tail-pill offset + inbox-pill
top all derive from this variable, so they follow automatically.
- `footer .banner-thin { margin-bottom: 0.8em }` so the slug
doesn't crash into the divider + link line below it.
No JS changes. Build clean.
