   see the comment above ChatScreen's return in chat.js for the full bk-8260f178
   history). Scoped to these two modifier classes ONLY: .yumi-main itself (frozen,
   _ds_bundle.css) keeps justify-content:safe center for every other screen routed
   through it (Settings, History, Connections, Usage), which the centering genuinely
   helps. Chat specifically measured ~70% dead viewport at 1280x720 with content
   centered inside the full flex:1 height — this packs it from the top instead. No
   effect once real content overflows the container (flex-start === safe center once
   content is taller than available height), so long transcripts are unchanged. */

/* bk-yumi5-usage-security-density (2026-07-18): re-measured live at 1280x720 — the
   flex-start override above still left a 379.7px (52.7%) dead gap between the last
   starter-chip and the composer, because .yumi-main-compact inherited the frozen
   .yumi-main's flex:1 (_ds_bundle.css) — the box itself still claims the FULL
   remaining height under the top bar, so no justify-content value fixes it: centering
   split the void above+below, flex-start just collapsed it to one gap below the
   content and above the composer (which sits OUTSIDE .yumi-main as a sibling, so
   nothing inside .yumi-main can pull it closer). The only change that actually closes
   that gap is letting the box SHRINK to its real content height (short hero +
   starter-chips) so .compwrap — the very next flex child in .yumi-shell's column —
   sits right below it. (An earlier attempt at flex:0 1 auto was reverted per the
   comment on .yumi-main-compact in _ds_bundle.css; re-tried here as the SCOPED
   app-extensions.css override in the SAME direction with the density math re-checked:
   any leftover height now trails after the composer as ordinary bottom page margin,
   not a void wedged between two functional controls — that's the actual defect this
   closes, not a global "zero whitespace anywhere" requirement.) */

/* bk-yumi5-mobile-header (2026-07-18): the mobile .top header (MobileTopRow, main.js)
   measured 156px tall, split into 3 stacked row-bands at 390x844. Two real causes,
   both fixed here:
   1) Stylesheet load-order collision, not a missing rule: _ds_bundle.css already
      hides the model-name/tier button at <=600px via `.model-badge-label{display:none}`
      (loads FIRST, see index.html), but this file's own unconditional
      `.model-badge-label-btn{display:inline-flex}` (same element, second class,
      EQUAL specificity, loads SECOND) wins the cascade and re-shows it — confirmed
      live: the badge-wrap measured 224px wide at 390px, containing the full
      "DeepSeek V4 Flash · Fast · Secure" button. That alone forced the icon row to
      overflow onto a 3rd line. Re-declared here, later in the same cascade position
      as the rule it needs to beat, so mobile keeps icon-only as originally intended.
   2) By design .top .sp gets flex-basis:100% at mobile (_ds_bundle.css) to force the
      brand onto its own row above the icon cluster — that alone is 2 rows, and the
      task's AC calls for ONE. With the label-btn fix above, the full icon cluster
      (lock + 4 round icon buttons) measures ~200px — comfortably under the ~362px
      available at 390px width alongside the ~95px brand mark — so collapsing back to
      a single flex row (no forced sp break, no wrap) fits with room to spare instead
      of needing a scroll/wrap fallback. */
