/* ===========================================================================
   Kwezr web brand kit
   ---------------------------------------------------------------------------
   The single stylesheet behind the public landing page. Organised as cascade
   layers so specificity stays predictable:

     tokens      design decisions only — colour, type, space, radius, elevation
     base        element defaults and the page shell
     components  every reusable block, prefixed `k-`
     utilities   single-purpose helpers, always last so they win

   Conventions
   -----------
   • Components are `k-<block>`, variants `k-<block>--<variant>`, parts
     `k-<block>__<part>`. Nothing outside this file should invent a `k-` class.
   • Never hard-code a colour, radius or spacing value in a component — read a
     token. Tokens are the only place a raw value belongs.
   • Direction is handled with logical properties (`inset-inline`,
     `padding-inline`, `margin-inline`) so Arabic RTL needs no overrides. Where
     a rule genuinely cannot be expressed logically, scope it to `[dir="rtl"]`.
   • Font files are referenced relatively so Django's ManifestStaticFilesStorage
     rewrites them to hashed paths during collectstatic.
