/* ============================================================================
   Sponsor Proposals — module stylesheet (v2 design system)
   ----------------------------------------------------------------------------
   Composer-driven archetype. Composes from canonical tokens in
   tokens/design-tokens.css (linked app-wide in the application layout):
   --color-*, --fg/-muted/-faint, --paper, --border/-strong, --surface-2,
   --font-sans/-mono, --r-input/-pill/-card/-modal, status semantic colors.

   Reskinned to the cool-slate / flat-white / square / dense aesthetic, with
   the saved show page mapped to archetypes/composer-driven/reference.html and
   the create + lockout flow to reference-create.html.

   PRESERVED VERBATIM (behavior-critical; the Stimulus controllers depend on
   these and they must not be renamed):
     - the `.sef-layout` grid driven by the --sp-chat-width custom property
     - the `.sef-layout--chat-collapsed` / `.sef-layout--resizing` states
     - the `.sef-resizer` drag affordance + `.sef-resizer--dragging`
     - the `.sef-tab` / `.sef-panel` tab-switch contract (`.active` + [hidden])
     - the `--sef-composer-height` anchor for the new-messages pill
     - the `.sef-account-picker:has(...)` selected-state toggle
