   Key Pharma — Core Scale Tokens (type, spacing, radii)
   Variables ONLY (no selectors besides :root), so this file is safe
   to include on ANY page: staff dashboard, standalone staff pages and
   the customer shop. Colours are intentionally NOT here: each surface
   keeps its own approved palette variables.

   CONSOLIDATION RULES (apply everywhere when replacing hard-coded px):
     font-size  9px  -> --text-2xs (10px)   minimum readable size
                10px -> --text-2xs
                15px -> --text-md (14px) for body/controls,
                        --text-lg (16px) for headings
                17px -> --text-lg (16px)
                18px -> --text-h3 (18px)
                22px -> --text-2xl (24px)
                26px/28px -> --text-3xl (28px)
                30px-34px -> --text-4xl (32px)
     spacing    1px borders/hairlines stay hard-coded
                3px  -> --space-0-5 (2px) or --space-1 (4px), nearest
                5px  -> --space-1 (4px);  7px -> --space-2 (8px)
                14px -> --space-3 (12px) or --space-4 (16px), nearest
                        to the surrounding rhythm
                18px -> --space-4 (16px) or --space-5 (20px)
                28px -> --space-8 (32px); 36px -> --space-10 (40px)
                56px-64px -> --space-16 (64px)
   Values > 64px (layout widths, big empty-state padding) may stay px.
