Fuses the standalone ship-class designer (Phases 17/18) into a sidebar ship-class calculator.

Live results: empty/loaded mass, empty/loaded speed, attack, defence, bombing, cargo capacity.
Single-target goal-seek: pin one result, the model back-solves the one input it claims (attack→weapons, defence→shields, speed→drive, mass→cargo, loaded-mass→load); inverse math in pkg/calc/solve.go.
Modernization mode (per-block + total upgrade cost) reusing the design-area component.
Planet area: MAT-overridable single-turn ships/turn + turns/ship (pure ProduceShipsInTurn ported from the engine).
Auto reach circles on the map (1–3 turns) from the selected planet, driven by the design's speed.
pkg/calc single source: BombingPower and the per-turn ship-production loop extracted from the engine (engine now delegates); Ceil3 display rounding bridged to wasm.
Standalone designer view/route removed; table + menus open the calculator; long-lived calculator state survives tab switches.
Input validation (per-field red borders + tooltips), load capped at cargo capacity, ceil-to-3 display.

Go parity + Vitest + Playwright e2e green on gitea; deployed to dev. CAP/COL + realistic multi-turn forecast deferred to Phase 34.

Fuse the standalone ship-class designer (Phases 17/18) into a sidebar calculator: live mass/speed/attack/defence/bombing results, a planet build-rate readout, single-target goal-seek, a modernization-cost mode, and auto reach circles on the map for the selected planet.

pkg/calc becomes the single source for the new math (no mirroring): extract BombingPower from the engine model and the per-turn ship-production loop from controller.ProduceShip into pkg/calc (engine now delegates), and add inverse goal-seek solvers in pkg/calc/solve.go. Thin-bridge the combat, planet-build, and solver functions through ui/core/calc + ui/wasm and rebuild core.wasm.

Remove the standalone designer view/route; the ship-classes table and the view/bottom menus open the calculator via a shared request store.

Docs: rewrite ui/PLAN.md Phase 30, adjust Phase 34 (realistic forecast + CAP/COL ownership), add ui/docs/calculator-ux.md, extend calc-bridge.md, fix navigation.md; remove ui/CALCULATOR.md.

fix(ui-calculator): keep calculator state long-lived; don't eject on planet click

Move the calculator's inputs into a page-level calculatorState singleton so they survive the sidebar unmounting the tab on a tab switch (the inspector auto-opens on a planet click). ensureGame resets the design when the active game changes.

While on the calculator, a planet click no longer switches to the inspector — the calculator consumes the selection in its planet area / reach circles. Halve the reach-circle stroke width.

- custom load capped at cargo capacity (error when exceeded); full load shows the cargo capacity; zero cargo pins load to empty and disables the toggle

- per-input red border + tooltip for every invalid value (blocks, techs, load, MAT, modernization target); no value may be negative; locking a speed is disabled when drive is zero

- display every computed number (results + goal-seek back-solved input) rounded up to 3 decimals via a shared pkg/calc Ceil3 bridged to wasm; engine keeps its own round-to-nearest util.Fixed*

- modernization total upgrade cost spans two columns (single line)
