feat(theme): promote industrial blueprint to the whole shell

Every scene now reads as the same FM doctrine: paper canvas + navy
frame + amber accent, 1px hairlines, square edges, monospace
uppercase labels, no glass, no shadows, no gradients.

WHAT CHANGED
- src/index.css rewritten end-to-end. Doctrinal hex tokens declared
  at :root, legacy --bg/--surface/--text/--primary/--border aliases
  repointed at doctrine values so existing component classes inherit
  the blueprint palette without per-component churn. Global
  * { border-radius: 0 } + box-shadow strip-out. All low-opacity
  tints via color-mix(in srgb, var(--bp-navy) X%, transparent) so no
  rgba() literals survive.
- Topbar redone as a 44px instrument strip: navy brand-lock with
  amber mark, uppercase mono tabs, amber-on-paper selected tab,
  square link buttons, mode pill with currentColor border.
- Mission Control hero + scenario tab strip + KPI cards retoken
  with amber underline on selected.
- Left rail: 1px-bordered KPI grid, queue cards stack as a single
  bordered list, agent supervision actions span the full width.
- Inspector: tabbed nav with amber selected, hairline-separated
  fields, square rule + run + evidence cards.
- Command palette: paper bg, amber-bordered selected item, mono
  caps headings.
- Live API console: paper drawer, mono call rows, amber filter chip,
  color-tokenised METHOD_COLOR map.
- Toaster: left-border accent on paper surface.
- Telemetry: navy gauges, mono row, square tick.
- Studio + Settings: shared studio-grid layout — paper panels in a
  1px navy grid with no margins between, mono inputs.
- Run History: mono table rows with amber selected filter chip.
- Landing: mono hero, square brand mark, stats strip as one
  bordered row, scenario cards in a 1px grid (no glow, no shadow,
  no gradient).
- Family accents in synthetic.ts and buildScenarios.ts retoken to
  doctrine hex. src/scenarios.json snapshot patched in place.
- Console.tsx METHOD_COLOR map → var(--bp-muted/info/amber/err).

AUDIT
- qa/palette_audit.mjs upgraded: scans 31 source files (.ts/.tsx/
  .json + index.css), catches rgb()/rgba()/hsl()/hsla() literals,
  and refuses named CSS colors (white/red/blue/...) as background/
  color/fill/stroke/border values. Hex regex uses (?![0-9a-fA-F])
  lookahead so deploy-id text like '#d3f1a' is not a false positive.
  Result: 0 non-doctrinal literals anywhere in src/.
- qa/smoke.mjs + qa/smoke_blueprint.mjs hasText matches converted
  to case-insensitive regex because the doctrine uppercases every
  user-visible label via text-transform: uppercase.
- qa/snap_all_scenes.mjs captures 9 fresh 1440x900 screenshots
  in qa/screenshots/v4/ (landing, mission procurement, mission AR
  blueprint, inspector raw, command palette, studio, settings,
  run history, mission live with console).

VERIFY
- tsc -b clean
- vite build green (CSS 41 KB / 8 KB gz, JS 851 KB / 230 KB gz)
- vitest 5 files / 24 tests green
- main smoke 27/27, 0 console errors
- blueprint smoke 15/15, 0 console errors
- palette audit clean (31 files)

ORACLE-REVIEWED
Round 1 PASS with <promise>VERIFIED</promise>. Two non-blocking
audit hardening notes landed in this same commit: scan JSON,
catch rgb/hsl/named CSS colors.

Confidence: high
Scope-risk: moderate (theme sweep, all scenes touched)
Not-tested: pixel-level visual diff vs prior theme (Oracle could
not inspect images this round; relied on programmatic checks)
