Nothing on the canvas overlaps

On a canvas narrower than 1,140 px the Viable pill moves up above the right end of the bottom bar instead of sliding under the right panel, so One-pager, Deck, FEA report and Benchmark keep their words at 1440 wide. The viability card and the zoom menu stay inside the canvas.

Two dimension values that meet in a view now step apart instead of printing over each other (the Periscope's head diameter and head height), and a callout pushed back inside the canvas is checked again where it lands. Checked on all seven Paras Defence products at three sizes: 0 overlaps.

Esc closes the viability card or the zoom menu first and puts focus back where it was, and Tab reaches the card right after its pill. Low-contrast chips, title-block cells and the zoom menu's hover now pass WCAG AA.

In Compare, picking a card answers in about 32 ms in a production build (it was 216 ms), a card reached with the keyboard is always scrolled into view, and Esc or Replace (on the card or in the panel) right after a pick act on what is on screen. Replace, the preview and the agent's swap_part use one rule for what may be fitted, and a swap of mixed parts no longer depends on the order they were listed in.
