name: "Fix fabric page — subsystem cards link to themselves, dropdown filters broken"
description: >
  Two bugs on /fabric page: (1) Subsystem cards always show all 12 tiles even when
  filtered, linking back to the same page — causes visual flicker/confusion. Fix:
  hide cards grid when filter active, show focused subsystem header instead. (2) Dropdown
  filter names (subsystem_filter, type_filter) don't match route params (subsystem,
  type) — dropdown filtering completely broken. Fix: rename select names to match
  route.

# T-227: Fix fabric page — subsystem cards link to themselves, dropdown filters broken

## Context

Subsystem cards on `/fabric` linked to `/fabric?subsystem=X` — the same page with a filter. All 12 cards showed even when filtered, making navigation feel like "going back to the same page." Additionally, dropdown filter `name` attributes didn't match what the route handler reads.

## Acceptance Criteria

### Agent
- [x] Subsystem cards hidden when a subsystem filter is active
- [x] Focused subsystem header shown instead when filtered
- [x] Dropdown `name` attributes match route params (`subsystem`, `type`)
- [x] Search input `hx-include` references updated to match new names

### Human
- [x] Filtered view looks clean and navigation feels intentional

## Verification

curl -sf http://localhost:3000/fabric -o /tmp/t227-fabric.html && grep -q 'name="subsystem"' /tmp/t227-fabric.html
curl -sf "http://localhost:3000/fabric?subsystem=context-fabric" -o /tmp/t227-filtered.html && grep -q 'border-left' /tmp/t227-filtered.html
